Personally I find it annoying when people come onto the forum to ask if their past convictions for drug taking or drink driving will cause them a problem in obtaining an airside pass, particularly when they try to mitigate their actions by apportioning part or all of the blame elsewhere. Becoming a professional pilot is a huge responsibility and requires people who take responsibility for their actions. So you may have "heard it before", but there might be a very good reason for that.
