Never do meth. Not only is it ignorant, but you'll be very ashamed of yourself afterward. I got a good fourty minute rush.. felt like I was the incredible hulk.. and just like that it disappeared and I felt like a fucking emo kid.. waiting to die.
Usually anything that doesn't come from nature I test chemically to make sure I'm not getting sold something like methamphetamine. However, one time nearly a year ago I did not test and I regret that decision ever since. 9:1 Sulfuric acid to formaldehyde (Marquis reagent) is particularly useful to test for meth as it will react to turn blood red in the presence of either methamphetamine or amphetamine. Like I said in prior posts, I am extremely skeptical of drug dealers (because you know they're such trustworthy people and all) and the claims that they make. Most often, they will simply attempt to sell you a common amphetamine instead of the relatively safe psychedelic chemical (that at the time was legal - woot!) that you ask for. Best bet just isn't to mess with them at all - go out into the woods and pick some 'shrooms I say.
But I digress, that
one time, I thought - "well, I've never been ripped off by this individual before, so I think the probability is high that I will not be ripped off this time" - WRONG. It became blatantly obvious that I had been sold an amphetamine substance (which I had never taken before but the effects are unique enough to discriminate), and I crashed so fucking hard that I was physically sick for four days straight. I couldn't keep any food down in the mornings, and I lost about ten pounds in weight. That's just after one time use.
Of all the chemicals one can ingest recreationally, meth is one of the most dangerous. Don't fuck with meth. I support an individuals right to recreational drug use, even if that use is decidedly against the law, but be smart about the chemicals that you choose to do. If you ever have to deal with the scum which are drug dealers, test test test.
