Surprisingly, there does not appear to be a comprehensive source of information relating to methamphetamine. While no list is ever complete, this one attempts to answer technical questions related to the chemical methamphetamine. Unfortunately, there tends to be a great deal of street lore that is blatantly wrong about methamphetamine and similar compounds. This document also attempts to point out some of the more common myths, and provide rational explanations. Do not use this information. I am not a chemist. This is for informational purposes only. Use of this information for illegal purposes is not condoned. The author makes no warranty, expressed or implied, of the suitability of this information for any particular purpose. The author does not endorse the abuse of any drugs, legal or otherwise. Methamphetamine also known as speed, meth, crystal, crank, and sometimes confusingly called ice is a chemical widely known for its stimulant properties on the human body. It is frequently confused with other drugs that share similar symptoms, including amphetamine, 4-methyl-aminorex, ephedrine, caffeine, and other chemicals, both legal and illegal. When precision is needed, we shall explicitly state one form or the other. The literature gives conflicting reports, due to the fact that many criterion are subjective, and probably also due to confusion over terminology. The pharmacological effects of methamphetamine are very similar to those of similarly structured molecules. Methamphetamine can be taken orally, snorted, smoked or injected, in approximately increasing order of immediacy of onset. Onset can be immediate in the case of injection , or can take as long as minutes if ingested orally. Duration is subjective, but is probably on the order of 4 — 8 hours. Delayed absorption for example, due to oral ingestion can prolong the effects relative to time of administration. Of course, larger doses last longer due to the fact that it is removed from the blood at a finite rate. The length of time that methamphetamine will stay in the plasma blood is between 4 to 6 hours. It can be detected in the urine one hour after use and up to 48 hours after use. A toxic reaction or overdose can occur at relatively low levels, 50 milligrams of pure drug for a non-tolerant user. These include euphoria, hyperexcitability, extreme nervousness, accelerated heartbeat, sweating, dizziness, restlessness, insomnia, tooth grinding, incessant talking, and other effects. Methamphetamine and other CNS stimulants have strong bronchodilation effects. Vasoconstriction tightening of blood vessels and pupil dilation are also common. Elevated blood pressure, heart rate, and other general symptoms of increased sympathetic nervous activity. The physical effects are almost assuredly due to interactions between the amphetamine structure and human physiology, probably due to the similarity to adrenaline epinephrine. Mental capacity is not diminished directly by the drug. In fact, some studies have shown slight increases in mental capacity on simple tasks. It has been prescribed for attention deficit disorder, among other things. Emotional responses may range from euphoria to anger and paranoia. Preliminary doses tend to produce the former, while continued use e. This is the easiest section to write, and the most fun, since I can be relatively sure of the facts. The basic structure is unchanged, but an HCl molecule has become attracted to the free base. In this case, the hydrogen from the HCl has become attracted to the nitrogen in the free base. You will notice that the salt form is much more common. This is for physiological reasons. The same reaction which attracts the free base to HCl could also attract it to other molecules, causing irritation and other symptoms. The d- is cool, the l- is shit, remember. Manufacturing methamphetamine, on the other hand, requires the use of not just ether, but reducing agents such as LiAlH 4. There are other recipes, but none to practical to attempt. Apartment manufacture of meth is not possible. The benefit of this method is that different amines can be used to produce novel N-alkyl amphetamines ethamphetamine, tert-butylamphetamine, etc. The only difference between methamphetamine and pseudo ephedrine is that damn alpha-hydroxy group. Reacting your ephedrine with thionyl chloride replaces the OH with Cl to produce N-methyl-alpha-chloroamphetamine as an intermediate. Hydrogenating this product is easy: The product of this step is N-methylamphetamine and HCl. Evaporate off the water and you have methamphetamine hydrochloride. If you start with dl-ephedrine, you get dl-meth. In this procedure, the alcohol grouping of ephedrine, pseudoephedrine, or PPA is reduced by boiling one of these compounds in a mixture of hydroiodic acid and red phosphorus. Hydroiodic acid works as a reducing agent because its dissociates at higher temperatures to iodine and hydrogen, which does the reducing. The dissociation is reversible. The equilibrium is shifted in favor of dissociation by adding red phosphorus to the mixture. The red phosphorus reacts with the iodine to produce PI 3 , which then further reacts with water to form phosphorus acid and more hydroiodic acid. Since the hydrogen atom of the HI is being absorbed by the ephedrine, the red phosphorus acts as a recycler. In some reductions, the need for HI is dispensed with just by mixing red phosphorus and iodine crystals in a water solution. The red phosphorus then goes on to make HI by the above mentioned process. With a small amount of due care, this is an excellent alternative to either purchasing, stealing, or making your own pure hydroiodic acid. This method has the advantage of being easy to do. It was formerly the most popular method of making meth from ephedrine. Now red phosphorus is on the California list of less restricted chemicals, so an increased level of subterfuge is called for to obtain significant amounts. One might think that this is easily gotten around by making your own red phosphorus, but this is a process I would not want to undertake. Ever hear of phosphorus shells? I would much rather face the danger of exploding champagne bottles. Those who insist on finding out for themselves, will see Journal of the American Chemical Society, volume 68, page Those with a knack for scrounging from industrial sources will profit from knowing that red phosphorus is used in large quantities in the fireworks and matchmaking industries. The determined experimenter could obtain a pile of red phosphorus by scraping off the striking pads of matchbooks with a sharp knife. Naturally, it is a tedious process to get large amounts of red phosphorus by scraping the striking pads off matchbooks. Another problem with this method is that it can produce a pretty crude product if some simple precautions are not followed. From checking out typical samples of street meth, it seems basic precautions are routinely ignored. I believe that the by-products in the garbage meth are iodoephedrine, and the previously mentioned azirine. If a careful fractional distillation is done, these products can be removed. They can be avoided in the first place if, when making hydroiodic acid from iodine and red phosphorus, the acid is prepared first, and allowed to come to complete reaction for 20 minutes before adding the ephedrine to it. This will be a hassle for some, because the obvious procedure to follow is to use the water extract of the ephedrine pills to make the HI in. The way around the roadblock here is to just boil off some more of the water from the ephedrine pill extract, and make the acid mixture in fresh pure water. Since the production of HI from iodine and red phosphorus gives off a good deal of heat, it is wise to chill the mixture in ice, and slowly add the iodine crystals to the red phosphorus-water mixture. To do the reaction, a ml round bottom flask is filled with grams of ephedrine hydrochloride or PPA-HCl. The use of the sulfate salt is unacceptable because HI reduces the sulfate ion, so this interferes with the reaction. This same acid and red phosphorus mixture can be prepared from adding grams of iodine crystals to grams of red phosphorus in ml of water. This should produce the strong hydroiodic acid solution needed. I can tell you that experiments have shown that one molar HI is ineffective at reducing ephedrine to meth. I would think that so long as one is over 3 molar acid, the reaction will work. With the ingredients mixed together in the flask, a condenser is attached to the flask, and the mixture is boiled for one day. This length of time is needed for best yields and highest octane numbers on the product. While it is cooking, the mixture is quite red and messy looking from the red phosphorus floating around in it. When one day of boiling under reflux is up, the flask is allowed to cool, then it is diluted with an equal volume of water. Next, the red phosphorus is filtered out. A series of doubled up coffee filters will work to get out all the red phosphorus, but real filter paper is better. The filtered solution should look a golden color. A red color may indicate that all the phosphorus is not yet out. If so, it is filtered again. The filtered-out phosphorus can be saved for use in the next batch. If filtering does not remove the red color, there may be iodine floating around the solution. It can be removed by adding a few dashes of sodium bisulfate or sodium thiosulfate. The next step in processing the batch is to neutralize the acid. A strong lye solution is mixed up and added to the batch with shaking until the batch is strongly basic. This brings the meth out as liquid free base floating on top of the water. The strongly basic solution is shaken vigorously to ensure that all the meth has been converted to the free base. With free base meth now obtained, the next step, as usual, is to form the crystalline hydrochloride salt of meth. To do this, a few hundred mls of toluene is added to the batch, and the meth free base extracted out as usual. If this is the case, the product is sufficiently pure to make nice white crystals just by bubbling dry HCl gas through the toluene extract as described in Chapter 5. If the toluene extract is darker colored, a distillation is called for to get pure meth free base. The procedure for that is also described in Chapter 5. The yield of pure methamphetamine hydrochloride should be from to grams. All the chemicals were reagent grade, with no special treatment of the tetrahydrofuran THF , and the atmosphere above the condensed ammonia was not flushed with nitrogen gas. A condenser was fitted in the center neck, an additional funnel containing l-ephedrine base in THF was fitted into one side neck, and a rubber stopper fitted with a glass tube extending to the bottom of the flask was fitted in the third neck. Anhydrous ammonia gas was condensed and collected in the flask. Small pieces of lithium metal were rinsed in petroleum ether, patted dry, and added to the condensed ammonia. A deep royal blue color was noted as the lithium metal dissolved in the condensed ammonia. The l-ephedrine was added drop wise to the lithium ammonia solution over a period of approximately 10 minutes with stirring. When all of the l-ephedrine had been added, ammonium chloride was added slowly to the solution. The flask was removed from the cooling bath, and the condensed ammonia was allowed to warm to room temperature and evaporate from the flask through the side necks. When most of the ammonia had evaporated, water was added to the remaining solution until it cleared and any remaining lithium metal was decomposed. The remaining solution was removed from the flask to a separatory funnel, where the aqueous layer was discarded. The THF layer was dried with magnesium sulfate, and the hydrochloride salt of the methamphetamine was made by bubbling hydrogen chloride through the THF. The same procedure was used, substituting phenylproponolamine and methylephedrine as the starting materials. A second synthesis was conducted with l-ephedrine, using the same procedure except that the reaction was not quenched with ammonium chloride. The reaction was found to reduce l-ephedrine to d-methamphetamine quickly and easily. Furthermore, it was found that the reaction converted phenylpropanolamine to amphetamine and methylephedrine to dimethylamphetamine. The time required for the reaction to proceed from the condensing of the ammonia gas in the reaction flask until the excess lithium was decomposed was approximately one hour. The majority of this time was spent waiting for the condensed ammonia to evaporate from the reaction flask. It was also found that the ephedrine would reduce to methamphetamine without the addition of ammonium chloride as a quenching agent. According to the infamous J. All in all, quite an entertaining and educational article ;-. This may be so in fact I read the same article , but typically a water quench leads to the alcohol, which is what we were trying to get rid of to start with. Apparently they were following the guys handwritten notes. Yep — apparently that would be the case. As well, any extra Li or Na if doing the straight Birch method would convert to the Hydroxide, which might fuck the product up a bit. Phenylalanine is 2-aminophenylpropanoic acid, which is more or less amphetamine with a COOH where the CH3 should be at the end of the chain. When that carbonyl is reduced, you now have amphetamine. Go back up to that first one I mentioned for upgrading amphetamine into methamphetamine. These are methods that are subjectively evaluated to be less useful, but still may serve as interesting lessons in applied chemistry. One of the easiest ways to make methamphetamine is from amphetamine. The difference between amphetamine and methamphetamine is the addition of a single methyl group CH 3 to the amino group sticking off the middle carbon atom in the chain. Fortunately, substituting amines is really simple. Vaporize your amine your amphetamine with a bunch of vaporized chloromethane CH 3 Cl, a solvent and some gaseous pyridine… voila, the amino group takes the methyl from the chloromethane and lets a hydrogen go. The hydrogen joins the liberated chlorine, and the resulting HCl is soaked up by the pyridine. The pyridine is optional. This last question is solved be reference to a principle called the law of mass action. An excess of methylamine will inhibit the secondary reactions. Typically, a reductive amination done in a parr bomb or using sodium cyanoborohydride is done with a five times molar excess of methylamine or methylamine hydrochloride. As with any distillation there will be some left over. Question is, how much ammonia and reducing agent are you willing to waste on making 2aminopropane? This tends to occlude a slight amount of solvent so keep your crystal size small and grind and dry the result. Both these solvents are easily available if you know where to look. Methamphetamine in its pure hydrochloride salt form is colorless. However, products on the market today are often not colorless. The following is a table of some common impurities and the colors associated with them. There is no doubt a segment of the dealers who will add food coloring or some other such color to their drug to make it more appealing, with the philosophy that a brightly-colored product may sell better than an off color product. This is relatively uncommon however. I am not sure what the cause of this is, but its most likely some form of oil, either formed in the reaction or left over from a very poor solvent. It may or may not be harmless depending upon what it is. This oil is often removed with acetone, but ethyl-ether would be better suited for this as it dries faster. Pure methamphetamine HCl melts at around c f. The crystals can be carefully chopped and mixed with sodium carbonate, and when the resulting powder is heated and the methamphetamine HCl melts CO 2 and methamphetamine base vapor is given off. This is probably one of the more effective ways of smoking meth if you are careful, however the hydrochloride salt is often the form smoked as the base form is often an oil and is difficult to store, transport, and work with. You can test methamphetamine HCl for optical activity with the greyish-clear plastic pieces from a pocket video game. Dissolve the methamphetamine in distilled water, then place one of the optical filters the grayish clear things from the games LCD display in front, and one in behind of the solution. Rotate one filter, and note the angle that is brightest and the angle that is darkest. After you have done this, repeat the procedure with distilled water. Or a dealer uses Ephedrine as cut. It is advisable to become familiar with the many ways of synthesizing methcathinone from pseudo ephedrine, as just such a procedure can be used on freshly produced methamphetamine to verify that the pseudo ephedrine was in fact reduced. Suffice to say that it is sweet, pleasant, and to a cat-head, nirvana. You should become familiar with this as well, in order to be able to know if suspected methamphetamine is in fact actually methcathinone. It should first melt at over c then begin to fume. Often the fumes will ignite. Methcathinone HCl has a higher melting point than methamphetamine HCl like over c at least and a characteristic smell, giving it away in an instant. Amphetamine has a bitter taste, followed by some degree of numbness. Methamphetamine is also more active on serotonin that amphetamine according to net resources. It appears to some extent in almost all syntheses relying on reduction and typically appears at the very end of the process of forming the HCl salt by bubbling HCl through the mixture. The scans just sucked when I tried to scan as text 5 pages magically became of scrambled text. I am currently trying gif type scans. However, it will never dry out as completely one might suspect. Even drying under heavy vacuum leads to only a temporary solution. Once it is exposed to air it quickly becomes an oil again. Often this is a brown color as you stated for other by-products. As far as the rest of the post, I find it very useful and agree with it completely. Take a ball about the size of a lead pellet, and wrap it in tissue, and swallow, or you can put it in capsules and use it. You can smoke it, mix it with vitamin B, and snort it like cocaine. Remember, this is pure stuff!! Take one of the small bottles and spray starter fluid in it till it looks half-full. Then fill the rest of the way with water, cap the bottle and shake for 5 minutes. Then, draw off the top layer with the eyedropper, and throw away the water layer. Repeat this until you have about 3 oz. Put the cap on it, and put it in the refrigerator if you can. It is very easy to become delirious off the ether fumes, so be sure you are well ventilated, I mean it!!! Small, aspirin, or experiment bottles seem to work the best for smaller batches. Remember, this is the water you have to use to evaporate. This recipe is bogus! You have simple extracted pseudoephedrine! All this stuff will give you is engziety sp? The d- isomer is the one that every one wants and that Uncle Sam has declared is just too cool for any one except doctors. The only way to change between the two isomers is to oxidize the l-meth into phenylacetone, condense it with methylamine, then reduce it. Ethyl Ether is very flammable and is heavier than air. Do not use ethyl ether near flame or non-sparkless motors. It is also an anaesthetic and can cause respiratory collapse if you inhale too much. Take the unmarked small bottle and spray starter fluid in it until it looks half-full. Let it sit for a minute or two, and tap the side to try and separate the clear upper layer. Then, draw off the top ether layer with the eyedropper, and throw away the lower water and cloudy layer. Place the ether in the marked container. Repeat this until you have about 1. Put the cap on it, and put it in the freezer if you can. Rinse the other bottle and let it stand. This is because the hydroxyl group the OH in ephedrine is on a very acidic carbon the first carbon away from the ring and a hydroxyl group is very basic. Your post was interesting, but this is not quite true. Direct hydrogenation over Pd or Pd on a carrier is well known and facile.
