Is Xylazine ever going to be safe enough to add to my psychnaut list

As a past K user this question pops into my dang skull more frequently, I'm lost on how this is so dangerous..and (what I'm posibly missing is that it's too neurotoxic) that there is no way to dose it safety? Like if I had a bag of straight xy and I did a little toothpick waited 5 min, wait 10min, etc that it will automatically start the necrosis and eating My skin? Like I said I could be missing a crucial piece like it only works IV (Very unlikely)

I feel like if someone can explain the difference between great K, and. Bag of xyl, that would be used very carfully(allegedly)...can't be enjoyable someone

If it's the contamination, I'm sure there's a way to wash and not lose alot of product. (Not that alot seems needed.

I'd appreciate a well versed commentor to help me understand why I could be asking something extremely ignorant.

I'm not the one to judge Amy personal experience, I just love to learn to prevent misinformation.
