Users report feeling a "rush" or surge of pleasurable sensation.

Heroin is particularly addictive because it enters the brain so rapidly. The effects are almost immediate and the user may initially feel sick. A feeling of calm and warmth then spreads through the body and any troubles or pains seem very distant and unimportant.  This "high" will continue until the effects wear off, usually 6 to 8 hours after a hit. The user will then need to start thinking about where to score and/or where...
