There is now an emerging body of scientific evidence that some of the active components of cannabis can have therapeutic effects. The harms are not all equally probable either.
Around that time some started using the drug for nonmedical purposes But it would not seek to restrict a cannabis activity simply because there may be some probability of it being harmful.
As noted, a substantial proportion of all drug offences in Australia are cannabis related ones nearly 70 per cent. Australia has passed laws, but has not put them into effect, and the United States has not made any allowances, leaving marijuana in the same category with other illegal drugs and allowing for prosecution if a person is found to be growing, possessing or using marijuana, regardless of the reasons Other studies have shown no increase in use, even among teens.
This includes impairment of memory, attention, and capacities to organise and integrate complex information. Harm minimising cannabis legislation will target cannabis related harm.
