1 Breathing problems. 2  Marijuana smoke irritates the lungs, and frequent marijuana smokers can have the same breathing problems that tobacco smokers have. 3  These problems include daily cough and phlegm, more frequent lung illness, and a higher risk of lung infections.
No matter how you use marijuana, the drug can cause immediate and long-term effects, such as changes in perception and increased heart rate. Over time, smoking marijuana may cause chronic cough and other health issues. The effects of marijuana on the body are often immediate. Longer-term effects may depend on how you take it, how much you use, and how often you use it. The exact effects are hard to determine because marijuana has been illegal in the U.S., making studies difficult and expensive to conduct.
