Marijuana Risks and Benefits: What do US Adults Believe? With the legalization of medical marijuana in 30 states and recreational marijuana in 8 states, the public perception of marijuana use is changing. Using an online survey that asked 16 280 US adults for levels of agreement on statements covering marijuana risks and benefits (safety, health effects, etc), authors of a new study in Annals of Internal Medicine found that respondents now believe that cannabis products are in some instances almost as helpful as they were once perceived harmful. So what do US adults believe? Take our 8-question quiz above to find out.
Question 1. National surveys suggest that the perception of "great risk" from weekly use of marijuana dropped from approximately 50% in 2002 to what percentage in 2014?
Answer: C. ~33%. National surveys suggest that the perception of "great risk" from weekly use of marijuana dropped from 50.4% in 2002 to 33.3% in 2014.
Answer: C. 50.1%. Half of US adults believe that marijuana is somewhat addictive vs 25.9% who believe it is very addictive and 22.4% who believe that marijuana is not addictive at all.
Question 3. True or false? Two-thirds of US adults believe that marijuana has at least 1 benefit including pain management and anxiety relief.
Answer: B. False. Approximately 81% of US adults believe that marijuana has at least 1 benefit including pain management and anxiety relief vs 17% who believe it has no benefit.
Answer: B. Pain management. Two-thirds (66%) of US adults believe marijuana helps manage pain followed by 48% who believe it helps with the treatment of diseases (eg, epilepsy and multiple sclerosis) even though there is limited evidence to support that; 47% believe marijuana can help relieve stress, anxiety, and depression, but efficacy and safety have not been established and possible harms may exist for that treatment.
Question 5. What percentage of US adults strongly or somewhat strongly agree that smoking or vaping marijuana prevents health problems?
Answer: C. ~30%. Approximately 30% (29.2%) of US adults strongly or somewhat strongly agree that smoking or vaping marijuana prevents health problems. More than one third (36.9%) strongly or somewhat strongly agree that edible marijuana can prevent health problems.
