Meth (methamphetamines) are stimulant drugs which allow individuals to stay awake for longer periods of time with less need for sleep which seems like a
good thing on paper, however it ain't a
good thing the next day when you have the comedown and have a feeling of emptiness due to the a sharp decrease in serotonin after the initial increase subsequent to taking the drug. Meth can be swallowed or snorted (bumping) which can lead to the user getting an intense high, however injections create an even quicker response as it enters the bloodstream quicker.
