There are vintage cigarette advertisements that claim that smoking is healthy for you. When cigarettes were first being mass-produced many years ago, people were unaware of the dangers of smoking them, and ads even encouraged people to smoke for their health. Do you think that it is possible that this could happen with marijuana in the future? Will humans look back and wonder, 'how could people think that smoking marijuana was healthy?' Even though marijuana has been around for a long time, researchers are still studying it and finding negative health consequences for marijuana users, despite it's growing popularity. What do you think?
