Yeah it will. You will become faster, stronger, and more atheltic. The other players are going to say wtf, how did you get so strong and don’t tell me spinach. You are going to get all the girls and the money and the fame.

No, especially if you vaporize most of the time. This avoids all chance of lung damage and besides that marijuana use over periods of years have still not done significant and permanent lung damage.

Depends if you’re smoking sativa or indica strains. Sativa would probably affect your playing more positively while Indica would just make your body too “stoned” to play. I used to smoke with Sativa/Indica mixed and do work around the house and yard. It made me super clear headed and didn’t leave me feeling tired, quite the opposite actually. So, yes it will affect your playing depending on what type and strain you smoked.

Hope this helped.

You can also google “sativa vs indica strains” and it will bring up a list of strains and effects it has.
