The American Heart Association has some bad news for weed smokers. The association released a new statement based on studies claiming that marijuana is not good for the heart. “The American Heart Association recommends that people not smoke or irritate any substances, including cannabis products, because of the potential harm to the heart, lungs, and blood vessels,” said Dr. Rose Marie Robertson, head of deputy of sciences and doctors of the. American Heart Association, in a statement. The warning is already obvious, most people know that inhaling smoke is not best for the heart and lungs. Therefore, coughing, the body struggles to eliminate smoke because it is harmful.

The new scientific statement, released Wednesday, used existing information and studies to draw conclusions about weeds and the heart. The statement says marijuana has “the potential to interfere with prescribed medications”

; and also “trigger cardiovascular conditions or events, such as heart attacks and strokes,” according to clinical pharmacologist Robert Page II. However, Page did not completely discourage marijuana use.

“If people choose to use cannabis for its medicinal or recreational effects, oral and topical forms, for which doses can be measured, can reduce some of the potential harm,” Page said in a statement. For those living in states where marijuana is legal, Page encourages them to stay away from drug traffickers. “It is also vitally important that people only use legal cannabis products because there are no controls on the quality or content of cannabis products sold on the street,” he stated.
