My son who just turned 19, started his Freshman year in college this past Fall. His grades are ok, but he constantly smokes pot and hangs out with friends that do the same. His mom and I (we're divorced but amicable) have talked to him about it, but to no avail. He sees nothing wrong with it, except that it's illegal. He has also experienced depression and has been in and out of counseling and on antidepressants, which he refuses to take now. He has a choice to make before the Spring semester begins in less than 2 weeks. I told him that either he stop smoking pot (and not use any other drugs) or I would stop paying his car insurance, gas and meals for college. He would have to get a part time job to support his habit, buy his gas and food. I won't give him anymore money. If he chooses Pot over school and comes back home, he'll have to get a job also, because his mom and I won't enable/support his habit at home either. The other option is to commit to stop smoking Pot and submit to a visual drug test every 30 days. If he's clean, I'll continue paying his way through school. Any thoughts or advice would be appreciated.
