need help convincing a family member...

Lots of good docs on youtube.find something with Dr Lester Grinspoon. The Union is good

I'd look into good motivational sativas like C99. C99 can make me clean me whole house while enjoying it and I hate cleaning.

Some strains will make you pretty useless. Some won't. If you have to work and can function without, don't smoke before work. Makes it better in the evening anyway.
