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.
