Older adults metabolize THC more slowly. Body composition changes (more fat retention of cannabinoids). Many take prescription medications that may interact. Result: start at 1-2.5mg THC, even if you used cannabis recreationally decades ago — modern cannabis is significantly more potent than 1970s-1990s flower.
Sublingual tinctures: most controllable, mg-precise dosing, no smoke. Microdose edibles (2.5mg): easy to titrate, predictable curve. Topical balms for joint pain: non-intoxicating localized relief. CBN-formulated sleep edibles: gentler than pure-THC for sleep-onset.
Cannabis (particularly CBD) can affect how some prescription medications metabolize through the liver — blood thinners (warfarin), seizure meds, some antidepressants, some chemotherapy drugs. Consult your healthcare provider before adding cannabis or CBD if you take prescription medications.
