Learn about the mental and physical risks to one's health from regular marijuana use.
Like tobacco smoke, marijuana smoke is a mix of toxic substances.
Regular marijuana smokers may suffer the same symptoms as tobacco smokers, such as: The heart normally beats about 70 to 80 times a minute, but using marijuana can double that rate.This increased rate can put a lot of stress on the heart.Smoking marijuana can also cause an increased risk of stroke.Evidence clearly shows that using marijuana has health risks.As marijuana containing higher levels of tetrahydrocannabinol (THC) is becoming more commonplace, the use of this stronger type of marijuana can contribute to increased health risks.
In fact, today's marijuana is stronger than marijuana from many years ago.
Studies show that the average level of THC, the principal "mind-altering" component of marijuana, has increased by 300% to 400% over the last few decades.
Marijuana is the most widely used illegal drug among youth today.
Starting to use marijuana young can greatly increase physical and mental health risks. Youth are especially vulnerable to the health effects of marijuana use because adolescence is a critical time for brain development.
Having THC in the brain at such a critical time can therefore interfere with brain development and harm brain function.
It can also increase the risk of triggering a psychotic episode or a mental illness such as schizophrenia.
