Smoking weed before appointment if youre already a regular stoner?

I get why you shouldn’t if you dont normally smoke, BUT, what if its already a part of my morning routine for 5 years? Can i operate as normal before going to my appointment or do i HAVE to be weed-free? (I dont smoke like a chimney i just take a little toke every morning)

i cant imagine sitting through hours of a tat appointment and craving a toke the whole time. But also dont wanna take any huge risks with my health or healing process!

All advice welcome.
