Just an idea

What if bars handed out free drug tests? I’m not the smartest but I just think people should be able to know if they got spiked easily! I really didn’t know what subreddit to post this in but if there’s any flaws in my idea I would love to hear them! I don’t go to bars at all so I don’t know what happens there. I’ve only seen it videos/movies or shows. I hear stories of people getting spiked tho.
