Cristal Meth

Methamphetamine works in a similar way to amphetamine. However, since methamphetamine crosses the blood-brain barrier faster and the breakdown takes significantly longer, the effect is stronger and the intoxication lasts longer. The effects of a standard single dose of amphetamine last about six to eight hours. Methamphetamine can be intoxicated for up to 16 hours. Methamphetamine unfolds its great effects in the central nervous system mainly by interfering with the brain metabolism of the neurotransmitters serotonin and dopamine. Effects: Strong physical excitement, hunger and need for sleep are suppressed, dilation of the pupils, increased sex drive, disinhibition, increased self-esteem, euphoria, increased urge to talk ("Laberflash")
