“Currently people think (cannabis is) harmless,” reports lead study author Emilie Jouanjus, at the University Toulouse III -Paul Sabatier University in Toulouse, France.  “What I think is very important from my work is that we see cannabis use may lead to very serious complications on the cardiovascular system,” concluded Jouanjus.

Marijuana is among one of the most illicit drugs that may double the risk of stroke in young adults. From 2006 to 2010, scientists had found 35 reports of patients who were experiencing cardiovascular complications following the use of marijuana.  About 85% of the patients were men around the age of 34, according to They found that in nine of those cases, the patients died.

Marijuana is a mixture of leaves, stems, seeds and flowers make it sound harmless; however it has a chemical in it called delta-9-tetrahydrocannibinol, also known as THC. According to, marijuana is not only compounded of just plant, there are 400 other chemicals in this drug that can cause health problems. THC is the main psychoactive ingredient. Since the 1970’s, marijuana producers have increased the level of THC in the drug to around 10%.

After a few minutes of smoking marijuana, the heart starts beating more rapidly, increasing the BPM 20 or 50. According to, because of the lowering of blood pressure and the increase in beats per minute, the likeliness of a heart attack is now four times greater within the first hour after smoking it than it would be than if teens did use the drug.  Researchers have seen that the THC in marijuana weakens the immune system from fighting off diseases, which can cause severe health problems, added.
