Doctors are concerned about the effects of smoking marijuana among young people who are vulnerable to the coronavirus.
Weed smokers put themselves at risk of dying if they contract the coronavirus.
Weed smokers are among the COVID-19 high-risk categories and explains why more young people are succumbing to the virus in recent weeks.
Doctors say marijuana smoke weakens the heart muscles, putting weed smokers and vapers at higher risk of dying due to COVID-19. Doctors have previously linked weed smoking to deaths of young people who contract COVID-19.
"The American Heart Association recommends that people not smoke or vape any substance, including cannabis products, because of the potential harm to the heart, lungs and blood vessels," said Dr. Rose Marie Robertson, the deputy chief science and medical officer for the American Heart Association, in a statement.

In addition to COVID-19 risk factor, doctors also found weed smoking has "the potential to interfere with prescribed medications" as well as "trigger cardiovascular conditions or events, such as heart attacks and strokes," said clinical pharmacologist Robert Page II.
"If people choose to use cannabis for its medicinal or recreational effects, the oral and topical forms, for which doses can be measured, may reduce some of the potential harms," Page said in a statement.
"It is also vitally important that people only use legal cannabis products because there are no controls on the quality or the contents of cannabis products sold on the street," he added.
