Background: I acquired a gram of Glaucine HBr purely by chance. I purchased 2 packs of HBW seeds, and the seller threw in the gift of 1 gram of Glaucine (it was a mystery gift, I didn't know what I was getting until it arrived).

Based on reports from:
Tolerance
Build-up
develops within days of regular use; analgesic tolerance faster than respiratory depression tolerance
Reset
7–14 days for partial reset; full reset may take weeks — tolerance loss greatly increases overdose risk
Tolerance Decay
Full tolerance
1d
Half tolerance
21d
Baseline
~35d
Acute tolerance: develops within a single session — the reset numbers above apply after sustained heavy use, not after one binge. Within-session tachyphylaxis usually resets largely overnight.

Age: 21 Weight: 125 lbs Dosage: 200 mg oral in gel cap Setting: My apartment T0:00-Dosed. My roommate and one of my closest friends moved out today, I feel sad about his leaving because I am very bad at dealing with change. The decision to take this drug was rash and uncalculated.

As you would expect from a poppy based dissociative, the feeling is rather like DXM, but with fewer unpleasant side effects, although some people have experie...
