Strain matters, tolerance is a factor.

Some strains slow you down, give you massive couch lock. Need to be doing something where that is helpful, ie, coding, cad work, etc. Some strains make you want to get up and dance, rebuild your house, wash your car… and not miss a single detail.

Medicinal grade stuff tends to be a couch lock strain.

As tolerance levels go up they become more interchangeable. I tend to prefer couch lock strains as I use my brain more than my body.
