Regular cannabis use in adolescence approximately doubles the risks of dropping out of school and of negative brain and mental health effects in adulthood. Regular cannabis use in adolescence is also associated strongly with the use of other illicit drugs.

Research in the past 20 years has shown that driving while cannabis-impaired approximately doubles car crash risk and that around one in 10 regular cannabis users develop dependence. Cannabis smoking probably increases cardiovascular disease risk in middle-aged adults but its effects on respiratory function and respiratory cancer remain unclear, because most cannabis smokers have smoked or still smoke tobacco.

From the Washington State Liquor Control Board, 2013:

Marijuana is not harmless.
Marijuana impairs coordination and perception, affects learning and memory, and can increase anxiety, panic and paranoia. Research shows one in eight youth who use marijuana by age 14 become dependent.

Some of the risks of smoking marijuana vs. consuming marijuana-infused foods are different.
Inhaling any kind of smoke harms your lungs. Consuming marijuana-infused foods can also be dangerous because it takes longer to feel the effects. It’s easier to have too much because the effects are delayed.

Recreational marijuana use has age restrictions.
Only those 21 and older can possess marijuana, with a limit of 1 ounce of useable marijuana, 16 ounces in solid form, and 72 ounces in liquid form.

Where you can use marijuana is limited.
Marijuana cannot be used in view of the public. It is also not allowed on federal and most tribal lands.

The penalties for marijuana use for those under 21 can be severe.
If you are under 21, you can be charged with Minor in Possession. If you have more than 40 grams, it is a Class “C” felony ($10,000 fine and/or 10 years in jail).

It’s not okay for parents to share marijuana with their kids.
It is a felony to provide marijuana to any minor.
