TripSit summary
A fairly common and very strong CNS stimulant. It is sometimes prescribed in the form of desoxyn for ADHD and severe obesity. In low doses, methamphetamine can elevate mood, increase alertness, concentration, energy and reduces appetite. At higher doses, it can induce mania, psychosis and muscle degeneration among other issues. Tolerant users may report much higher doses than new users.
