Give it a cack
I wouldn’t be too concerned about what others have to say regarding your permiscuios behaviour.
The do gooders, christians and jahovas ranting and raving that you don’t have a chance, to reconsider your career options and the best you'll do for yourself is Coles or Woolies is just nonsense. However they are right about something, there’s no place for that sort of behaviour if you're serious about flying and it will certainly not be tolerated in a commercial environment.
If you have made a conscious decision that this is what you want to do with your life then stick to it.
LSD and speed aint the best things to be putting through your body, but neither is the copious amounts of alcohol young pilots drink on a weekly basis...but yet we always do it and will continue to do so until the day we work out we're not 10ft tall and bullet proof and other responsibilities set in.
In short if you've got no record, you're right, and don't go to your gp for a medical...he’s probably not a dame anyway.
Don’t mess with the law son and don’t touch the ****e again. You'll only have to fly seedy once to see its just not worth the hassle.
