As long as the effects of marijuana on the brain

Finally, scientists can answer the question that anyone who has ever taken the marijuana has asked how long this will last?

It is still a distance, but researchers at Alberta University discovered that cannabis still prevents learning up to 24 hours after consumption -- but the effects completely disappear until the third day.

The research team tested how long the cannabis will change their participants' ability to learn new information on this fact.

Much remains to be studied, but their research offers a starting point for the Canadian government to establish security instructions now that the country has legalized marijuana.
