Tough on Drugs

Marijuana abuse leads to blood flow problems in the brain and increased risks for heart problems. To understand the way that marijuana might cause these side-effects, NIH scientists measured proteins in the blood of marijuana abusers and found that heavy marijuana users show increased levels of a protein called apolipoprotein CIII which can cause increases in blood triglyceride levels. These findings might explain why marijuana users suffer from brain and cardiac problems.

Long-term harmful effects of marijuana (MJ) include risk for heart attacks and strokes in addition to impaired learning and memory. The active chemical in MJ called delta-9-tetrahyrdocannabinol (THC) is believed to exert these effects by binding to cannabinoid (CB) receptors located on several cell types in various organs.
