I would say no. Just like with prescription drugs, recreational drugs can have bad side effects and/or interfere with or cause medical problems that you didn’t know you had. Like congenital problems that may not yet have been discovered by your doctor.
At least with prescription drugs, there are already warnings on the package about not using them if have X, Y or Z conditions. Recreational drugs have no warnings and since they have not been extensively tested (because they’re illegal) you have no real idea what they could do to you, even if all of your friends never had a bad reaction.
Also, with prescription drugs, you are being monitored by a physician. Not the case with recreational drugs. Even if something did go wrong, you wouldn’t be able to bring the package with you, you know the one with the true ingredients list, to show the emergency room doctors. In an emergency situation, time is everything.
My cousin is an emergency room nurse. She said illicit drug problems, alcohol related issues and car accidents are what she deals with the most. Oh, and then gunshot wounds, which are often the result of being high on illicit drugs or alcohol. Just sayin’
