Stimulants give one a feeling of exhilaration coupled with high energy and other effects like tremors, anxiety, panic, and paranoia. The physical effects include increased heart rate, blood pressure and body temperature. Long term effects can get nasty, starting with weight loss and insomnia, and progressing to cardiovascular complications, strokes, seizures, and nasal damage. However, in meth’s case, be sure to add severe dental problems as well.
For all each of these drugs, there is one final repercussion when used: that monkey on your back, addiction.
