People’s own experience with marijuana is highly related to their views on both questions.

Large majorities of adults who say they have ever tried marijuana — which is nearly half of Americans — think marijuana’s effects on users (70%) and society at large (66%) are positive.

Conversely, the majority of those who have never tried marijuana think its effects are negative: 72% say this about its effect on society and 62% about its effect on users.

Americans’ ambivalence about the effects of marijuana contrasts with their widespread support for legalization. According to Gallup’s latest measure, 68% of U.S. adults, tied for the record high, think marijuana should be legal.
