In case this case isn't already closed (sorry I'm tripping way too much to focus on all of the above posts)...
The only sensible advice and course of direction- seek other highs!
Get some Kratom. Just have some a couple days a week max if you like it.
So many people seem to love gabapentin.
Kanna is good stuff.
Mulungu even.
And I have to shout Kava!
These are all examples of things people do.
Right minded people DO NOT drink Isoproply for high's sake alone, not when there is such an array out there for the allergy free.
Im extremely allergic to most substances, including Kratom which I love.
I drink my kava, eat/vape my weed, and have just taken legit 6 mg's LSD in 9 days, well 5980ug to be precise. 980 ug this day?night?day's? trip lol.
Too much Etizolam as well, NOT recommended.
Heck, even just chew some Salvia Leaves. I have a bag actually, not gotten to trying that method. Plus 5× extract not tried for fear of severe allergy.
Fact- LSD is way less harmful (or maybe damaging) than Isopropyl Alcohol.
Plenty good, natural and other highs out there, far better, AND fit for purpose, IMO.
Sorry if this has all been spelled out already.
