Good thought, and kind, but remember- being there for him first, having a human being to talk with him is irreplacable versus smoking a joint, even if it could help ease the pain.

It's best not to distract ones self during such an emotional time, as feelings of this sort need to be felt raw so we can deal with them in a healthy, albeit painful way. But it helps in the long run to be able to sort it out.

Give it like 2 weeks, or so. Remember, weed should never be an escape from problems, rather, used as a healing aid to bring happiness and fun.

Good luck with everything.
