Smoked marijuana delivers THC and other cannabinoids to the body, but it also delivers harmful substances to users and their loved ones, including many of the same substances found in tobacco smoke that are harmful to the lungs and cardiovascular system .

Nearly 53 percent of people aged 18 or older who reported lifetime marijuana use say they first used marijuana between the ages of 12 and 17. About 2 percent report using marijuanafor the first time before the age of 12. In 2010, 21 percent of high school students had used marijuana in the past. 30 days, while 19 percent smoked cigarettes.

It is estimated that 9% of marijuana users eventually become addicted to it. For users who began using marijuana as teenagers, the percentage of those who become addicted is approximately 17%. Among those who smoke marijuana daily, the number who become addicted ranges from 25 to 50 percent. In 2010, of the 7.1 million Americans who abuse drugs, 4.5 million used marijuana. In 2009, about 18% of people seeking drug treatment reported marijuana as their primary drug. “Also in 2009, 61% of people under the age of 15 receiving treatment reported that marijuana was their primary drug of use.” Marijuana-related problems may occur during or after the first use of marijuana, or they may build up over time.

At very high doses, marijuana can also cause delusions and hallucinations. The legalization of recreational marijuana has had both positive and negative impacts. On the positive side, states where recreational marijuana is legal have enjoyed a significant increase in tax revenue. “Colorado, which was the first state to legalize the drug for recreational use for adults, generated $506 million in revenue from marijuana sales between January 2014 and July 2017, including more than $200 million in nothing than in 2016. A 2017 study also showed that if marijuana were legalized in the United States at the federal level, it would generate $132 billion in tax revenue and create more than a million jobs over the ten-year period./
