@donleypong, Absolutely you give massive social problem indeed conversation. Before reading this article I never accept to marijuana legalization. As my country marijuana, cannabis already banned and if sell or transportation given legal action against them. But everyone know they all doing via high class politicians. They cannot arrested in their government period. They used their political power. I told my country situation.
Marijuana usage can be addiction. Then lot of problem happen to younger age persons. They immediately addict to marijuana.

Here are three reasons that I believe it’s time to legalize marijuana
It Decreases the Use of Opioids, Which are Killing People
First, the United States is facing a drug problem of a different sort. Opioids are extremely addictive, they are far more dangerous than marijuana will ever be, and they are killing people in shocking numbers. Many people use prescription opioids for pain and then become addicted, or they obtain them illegally with the same result.

After read above contents I agree with marijuana legalization to USA. But need to controlling level. Exceed limit couldn't agree more. Thanks again posted term topic to community.
