Marijuana has never been a threat to us rather we have been the one that are threats to the innocent marijuana.

We abuse it, we misuse it, we over use it, we don't even care the right state of mind to use it.

Even medical drugs contains little bits of it to the dosage that is useful and it works, drug manufacturers are licensed to trade and use it because the are very cautious of the dosage impacts and effects while the lay persons don't. So we should speak of of its abuse and not usage.

We are the threats to our own selves and not marijuana.
