According to the survey of 1,122 adults conducted March 1-7, 56 percent of Americans find pot use to be socially acceptable, including 83 percent of marijuana users and 74 percent of those who have tried marijuana.

Yet when it comes to their own consumption, 31 percent of pot users prefer using marijuana alone. Forty-one percent get high with friends or other people outside their families.

But while they may consider it socially acceptable, many users — four in 10 — hide their weed, for various reasons, most often to keep it from children or grandchildren. The great majority (93 percent) of pot-using parents with underage children say they have not used it in front of or shared it with their children. But among parents who use marijuana and have adult children, 47 percent have used it in the presence of or shared it with their children.
