Thanks for the link. At least we now have a specific definition for "crystal meth" (methamphetamine hydrochloride). >This causes a user to want to repeat smoking much faster. I didn't see where they made that conclusion. I did see this: >>Despite much research data from animals in the literature,17 the areas of the human brain and the key neurochemicals that are responsible for the pleasurable effects of methamphetamine and for the transition from drug-liking to drug-craving are still unknown. >>"Research into the pharmacologic treatment of methamphetamine addiction has largely been limited to studies in animals. Surprisingly, there are very limited data from clinical trials of new therapies to prevent methamphetamine addiction relapse.24,33 Although animal studies are essential to the development of new medications, given the public health importance of this worldwide problem and the existence of potential drug targets, it is obvious that the very slow pace of clinical testing of new therapies in methamphetamine addiction needs to be accelerated.
