Shit happens, true. But shit happens more to dipshits.
I have spent hundreds of hours at the shooting range. How many times have I had any sort of accident? Zero. Because I used my damn head and respected my firearms no matter how experienced I was in using them.
Again, you are blaming the drug for what happened. Like I said before, if you didn't know the damn concentration, its your fault for not figuring it out. When you hop onto the fastest production road bike and crank the throttle, you flip and land on your ass because you didn't start slow.
I'm sorry for what happened to you, but don't add to the abundance of unqualified negativity here. If I shot myself in the foot because I didn't know I was using a super light trigger. I'd feel pretty fucking stupid.
