Omni Brain managed to find a wonderful Dutch website where the neurochemistry of common street drugs is illustrated as step-by-step animations.
If you ever wondered exactly how ecstasy, cannabis, speed, cocaine, heroine, alcohol or nicotine have their effect in the brain, now’s your chance to find out.
The animations give the detailed effects of the drugs on the neurotransmitter systems with an explanation of each of the main effects of the compounds.
