I've never heard ANYBODY say that weed gives them motivation to get shit done. wtf?
A buddy of mine has ADHD is Bipolar and a bunch of other crazy shit when he smokes he acts normal, is motivated and does well in his lectures.
One day he didn't take his meds or smoke I got home at 5 am and he couldn't even talk, stomping around shirtless with his eyes bugging out of his head just making animal noises.
Sorry I'll take his baked motivated normal self any day.
For a normal person adderal motivates more. For someone who adderal is prescribed to a nice Sativa probably keeps them motivated. Motivation and focus are two different things.
