Does Cocaine Cause Foul Vaginal Odour?

Can cocaine and/or molly cause vaginal odor? I ve only been using about 2 months, not heavily, but just for for fun here and there. I used to not have this smell, but I ve noticed it since after my first period after I started using the two drugs. I changed to pads instead of tampons, hoping that would correct the smell but it hasn t. The smell isn t everyday, but usually comes within the next day or two after using. Help!!
