Can My Doctor Hold My License For Cannabis Being In

Can my doctor hold my license for cannabis being in my system ? I have a bad feeling about this doctor.. He touches me but he knows I don't like that and he gave my dad medication that literally made him lose his memory... Sounds made up but Doctor victor van is his name and he has made my life hell, 1 time he even went as far as calling me fat ? Is this normal practice ? 1 time I went there with a dislocated shoulder and he recommended vitamin b 12 and that is all he recommended me taking......... Please look into this, please !
