I will be selfpay. Here is my question. When you go in for the tests you get screened for drugs in your system. Is that correct? I ask because I am a regular user of marijuana. Will I get turned down for this. The only drug I use is marijuana, nothing else. Not even asprin. Will a Mexican doc turn a blind eye to this or will I be rejected. Please dont critisize me for this, I am just looking for a factual answer.
