A new poll has found that 75 percent of Americans believe that the sale of marijuana will eventually become legal across the nation—whether they supported legalization or not.

The Pew Research Center Poll, conducted in mid-February among 1,821 adults, also found that the number of people in favor of legalizing pot continues to grow. Four years ago, 52 percent of people said they thought marijuana use should not be legal. Now, 54 percent are in favor of marijuana legalization.

The survey also found that the public believes marijuana to be less harmful than alcohol. Sixty-nine percent of people believed alcohol was more harmful to a person’s health than marijuana, with only 15 percent saying that they believed marijuana was more harmful. Similarly, 63 percent of people believed alcohol was more harmful to society in general than alcohol. A large majority of people surveyed (76 percent) believed that people convicted for possession of small amounts of weed should not have to serve jail time.
