marijuana
Marijuana is the most commonly used illegal drug in the United States. [5]
Did you know?
The potency of today's marijuana has increased significantly over the past few decades. [2, 3]
The amount of the main mind-altering chemical, THC, is considerably stronger, as it's been modified to have increased effects.
Plant marijuana products:
1970s: 1-3 % THC
1990s: 4% THC
Current: 18-23% THC
Extracts and concentrates:
Extracts and concentrates commonly used in various types of vaping or dabbing devices, tinctures, topicals, and edibles can contain an average of 50% up to 90% THC.
So what does this actually mean?
For someone new to the drug, it may mean exposure to higher concentrations of THC, with a greater chance of a negative or unpredictable reaction.
For those more experienced with marijuana, it may mean a greater risk for addiction if they are exposing themselves to high doses on a regular basis.
Marijuana is addictive. [2, 5]
Approximately 1 in 10 adult users become addicted.
When use starts in adolescence before age 18, the rate of addiction rises to 1 in 6.
Marijuana accounts for the largest percentage of treatment admissions - almost 50% among those 12 to 17 years old.
In addition, the increasing strength of marijuana is leading to higher rates of addiction and mental health concerns.
methods of consumption
smoking
Usually via joint, pipe, or bong.
Users roll loose marijuana into a cigarette ("joint") or smoke it in a pipe or water pipe ("bong") or in a cigar ("blunt")
vaping
Vaporizers heat marijuana to release its THC and vapor is inhaled
Dabbing/Hash Oil
THC is extracted from marijuana creating hash or honey oil (a goey substance), wax or butter (soft, lip balm-like substance), and shatter (a hard, solid substance)
The production of dabs is a dangerous process in which butane gas is used to extract the THC.
edibles
Beverages or food
Can be mixed into food or brewed as tea and ingested. In states where marijuana has become legalized, more edibles are being sold, including baked goods and candy that closely resemble well-known foods (e.g., brownies, chocolate, cookies, gummy bears).

Smoking marijuana is just as harmful as smoking cigarettes. [1]
-
Marijuana smoke and tobacco smoke are actually rather similar.
-
Benzopyrene, a carcinogen, is found in both marijuana and tobacco smoke, but in greater concentrations in marijuana smoke.
-
-
Marijuana smoke typically is inhaled more deeply into the lungs and held in 4x as long as tobacco smoke, giving toxins greater access to the cardiovascular system.
-
Marijuana contains over 400 chemicals, and smoking marijuana elevates heart rate, suppresses the production of hormones regulating the reproductive system, and unequivocally impairs lung function.
-
All use equals risk, and the healthiest environment for teen lungs is a smoke-free one.
-
-
Smoking marijuana is NOT safer than smoking tobacco.
Marijuana hurts people.
-
Sometimes people believe marijuana is safe because it is a natural plant from the earth which is most often used in its natural form. The body does not know or care whether a drug is man-made or grown in the ground.
-
A large variety of addictive substances, from the nicotine in tobacco to the opium in poppies, come from nature.
-
Marijuana, even in its most natural forms, has been proven to carry both health and safety risks.
-
-
Toxicity from edibles
-
Edibles give users a different kind of high than the one they get from smoking marijuana, largely because the pot is absorbed through the stomach instead of the lungs.

-
Addiction
-
Quality of life

Negative impact on school and job: reduced grades, enrollment gaps, and lower income as adults
