No. Don’t even think about it.
The sale and use of marijuana are still illegal in the United States under federal law and if someone is caught with marijuana he or she will be panelized with a fine and go to prison as well. Such criminal activity can also get you banned from getting admission to any university in the United States.
You may face fines from $500 to $5,000. It is also illegal to buy cannabis in Canada and try to take it across the border.
