Thank you for this extract. Iv seen many past meta analysis on the 7 to 14 day impairment but no difference after that. Based on these findings i use marijuana regularly but never in periods of need of high output like fundraising, product release date sprint etc... There are a lot of parts of life when you have a lot of stress but you don't actually need to be on your top game you just need to show up for those periods weed is amazing.
