Cannabis with the right cannabanoids and terpenes.
Low THC, High CBG, Moderate CBD is the most relaxing way to enjoy imo.
I go for uplifting citrus or piney terpenes like Limonene, Pinene etc.
I like black Tea, with chamomile. A nice touch of stimulation as the caffeine combines with the thc but the chamomile has very mild gaba effects (fine I’d believe post benzo AWS) + black tea has theanine.
Ketamine is nice but incredibly addictive and damaging to the body IMO.
MDMA nice but once in a blue moon.
LSD can be more euphoric but way harder to ride; Mushrooms more reliable imo.
For me it’d be Cannabis or Psychs, maybe MDMA.
Id avoid addictive drugs personally if having come off benzos.
