This article isn't bad, but it's a very shallow, narrow view of things. In general it seems to make no distinction with addicts using high doses to overcome tolerance levels with recreational drug users in general. Methamphetamines and amphetamines are not the same chemical, despite being similar. https://methoide.fcm.arizona.edu/infocenter/index.cfm?stid=172 https://methoide.fcm.arizona.edu/infocenter/index.cfm?stid=1... The small differences between the molecules allow it to penetrate the blood brain barrier more efficiently, has longer lasting toxic effects and acts more as a central nervous system stimulant and >less peripheral nervous system and cardiovascular stimulation activity. Another difference between amphetamine and MA is that amphetamine stimulates the CNS indirectly by activating the release of catecholamines and inhibiting their breakdown and storage. In contrast, MA stimulates the postsynaptic catecholamine receptors directly.[2] Increased dosage is only one part of the difference between Methamphetamine and Amphetamines. Street meth is also far more likely to have fillers, leftover solvents and a bunch of other things that are not good for you. >In general, recreational drug users take their drugs at doses so much higher than psychiatric patients that they're basically two different chemicals Recreational drug users come in a wide range. The first two sections of the article speak about addicts doing extremely large doses, then seems to lump 'recreational drug users' altogether with that.
