MYTH: Marijuana is okay for some youth
FACTS: Research strongly suggests that marijuana use during adolescence and early adulthood can damage the part of the brain associated with learning and memory.1
Regular marijuana use during adolescence can lead to reduced IQ scores, poorer school performance,2 and higher school dropout rates.3
MYTH: Marijuana isn’t addictive
FACTS: From 2012-2015, marijuana has remained the most common primary drug of abuse among 12-18 year olds seeking publicly funded treatment services in Sonoma County.4
In FY 2014-2015, of the 344 youth entering treatment in Sonoma County, 244 or 71% sought treatment for marijuana addiction.5
Chronic marijuana use can lead to addiction. Research shows that approximately 9 percent, or about 1 in 11, of those who use marijuana will become addicted. This goes up to 17 percent in those who start using while young (in their teens) and increases to 25-50 percent of daily users.6
Long-term marijuana users trying to quit report various withdrawal symptoms, including irritability, sleeplessness, decreased appetite, anxiety, and drug craving.7
MYTH: Marijuana is safe to use during pregnancy and breastfeeding
FACTS: Marijuana use in pregnancy may affect the baby’s brain development and when the child reaches school age, it may have problems with attention, behavior, memory, delayed reading skills, and depression.8
Using marijuana during pregnancy is as serious as cigarette smoking or alcohol consumption. Marijuana is not recommended, even for medicinal purposes— during preconception, pregnancy, or lactation. There is no safe level for marijuana use in pregnancy.9 10
Research strongly suggests that use of marijuana during pregnancy can lead to low birth weight, premature babies, small full-term babies, and hospital stays in the special newborn care nursery.11
Breastfed infants are exposed at unhealthy levels. The active ingredient in marijuana, THC, builds up in the breast milk of marijuana-using mothers, and when nursing, comes out in their breast milk. With chronic, heavy use, THC levels can be 8 times higher in breast milk than in the mother’s blood.12
MYTH: Marijuana has minimal impact on driving, road safety and crime
FACTS: Marijuana significantly impairs judgment, motor coordination, and reaction time. Studies have found a direct relationship between the concentration of marijuana (THC) in the blood and driving ability. The risk of being involved in an accident doubles after marijuana use.13
Accident-involved drivers with THC in their blood, particularly higher levels, are three to seven times more likely to be responsible for the accident than drivers who had not used drugs or alcohol.14
The risk associated with marijuana in combination with alcohol appears to be greater than that for either drug by itself.15
MYTH: Marijuana helps one’s mood and promotes mental health
FACTS: Like alcohol, marijuana and associated THC-containing products are intoxicants and can contribute to impaired judgment and increased susceptibility to mental health problems, including depression, insomnia and paranoid delusions.16
There is a significant risk of relapse or worsening of symptoms for individuals with psychotic disorders.17
Regular marijuana use is correlated with an increased risk and/or worsening of the symptoms for individuals with anxiety, depression and psychotic illnesses.18
MYTH: Secondhand marijuana smoke is safe
FACTS: Smoking marijuana clearly damages the human lung, causing chronic bronchitis and injury to the cell linings of the large airways.19
Second hand smoke from burning marijuana has been shown to contain many of the same toxins, irritants and carcinogens as tobacco and wood burning smoke.20
In 2009, California added marijuana smoke to the list of chemicals known to cause cancer and reproductive toxicity under the Safe Drinking Water and Toxic Enforcement Act (Proposition 65). At least 33 individual constituents were identified in both marijuana smoke and tobacco smoke that contain 65 carcinogens.21
Infants who are exposed to second-hand marijuana smoke are at risk of sudden infant death syndrome (aka SIDS).22
