Quick answer

Body weight sets the ceiling for a starting dose, not the starting point. A 150-pound adult with no tolerance should begin at 1 to 2.5 mg of THC in a lozenge, not the 10 mg that simple weight math suggests. Use this band for a first session: under 130 lb, 1 to 2.5 mg; 130 to 180 lb, 2.5 to 5 mg; 180 to 230 lb, 5 to 7.5 mg; over 230 lb, 7.5 to 10 mg. Treat those numbers as upper limits you can work toward over several sessions. Liver enzyme activity, body fat percentage, and prior cannabis use shift the number more than pounds do.

Why weight matters, and how much

THC is fat soluble. A person with more adipose tissue stores more of the compound and releases it over a longer window, which can stretch the tail end of a lozenge high. A heavier person may also need slightly more THC to reach the same blood level, because the dose spreads through a larger volume of tissue. That is why weight belongs in the calculation.

Weight is not the strongest variable. The liver enzyme CYP2C9 and related pathways convert THC into the more potent 11-hydroxy-THC. People with fast enzyme activity feel a swallowed lozenge harder and faster than people with slow activity at the same weight. Swallowing the lozenge sends THC through first-pass liver metabolism, which produces that stronger metabolite. Holding it under the tongue sends most of the dose into the bloodstream directly and skips that conversion, which is why sublingual use feels flatter and more predictable.

Step-by-step dosing

  1. Read the THC and CBD milligrams printed on the lozenge package.
  2. Find your weight band above and take the low number of that range.
  3. Split the lozenge so the piece matches that milligram target.
  4. Place the piece under your tongue and hold it there for 60 to 90 seconds before you swallow.
  5. Wait at least 90 minutes before you judge the strength of the dose.
  6. Write down the milligram amount, the clock time, and how you felt at the two-hour mark.
  7. Increase the next session by 1 to 2.5 mg only if the first dose felt clearly too weak.

Timing for lozenges

Sublingual absorption starts within 15 to 45 minutes and peaks near 90 minutes. A swallowed lozenge takes 60 to 120 minutes to register and can run 4 to 8 hours. Do not redose inside the first two hours. Most bad experiences with lozenges come from stacking a second piece before the first one has finished arriving.

Adjusting after the first session

Move in steps of 1 to 2.5 mg, not 5 mg. Keep the same weight band and the same delivery method so the comparison is clean. If you switch from swallowing to holding under the tongue, drop back to your earlier dose and rebuild. Tolerance builds with daily use, so a dose that worked in week one may feel light by week three. Take two or three days off and the same milligram amount tends to hit harder again.
