Should it be legalised?
Yes , it should. First off it's very stress relieving.
Secondly there have been many test/experiments on how marijuana helps against diseases.
As shown here. http://legalizationofmarijuana.com/marijuana-facts.html
You can get alot of information on why it should or should not be legalized , here.
Are the people who are against legalising non-users?
The experience i had with non users is that they usually don't have an opinion on why it should be legalized here.
As for the some non users that are acquainted with ''stoners'.
I think it's still a 50/50% chance that they will want to legalise marijuana.
As it depends on what kind of experience the person has had with it.
Is it worse than alcohol?
No , definetly not. As a user of marijuana and alcohol , i think alcohol is worse.
Alcohol causes agression with many people. It also does more damage than marijuana.
Marijuana is more relaxing and soothing. Although it also has a negative effects sometimes.
But this is very rare. Alcohol on the other hand damages more frequently.
