One drop of a liquid cannabis concentrate usually contains 0.5 mg to 2 mg of THC in a standard tincture or oil. The exact number depends on the total THC in the bottle and the size of the dropper. Most droppers deliver about 20 drops per milliliter, which makes each drop roughly 0.05 mL.
How much THC is in one drop of cannabis concentrate?
A single drop from a standard tincture dropper holds about 0.05 mL of oil. If the bottle contains 300 mg of THC in 30 mL, that works out to 10 mg per mL, or 0.5 mg per drop. A stronger 900 mg bottle in the same 30 mL volume delivers 1.5 mg per drop.
High Potency Cannabis Concentrate Dosage Tips
Concentrated distillate is a different category. One mL of 85% THC distillate holds about 850 mg of THC, so a single drop could carry 40 mg or more. That is far beyond a beginner dose and is not how distillate is meant to be measured.
How do you calculate mg of THC per drop?
You need two numbers from the label: total THC in milligrams and total bottle volume in milliliters. Multiply the volume by 20 to get the drop count, then divide total THC by that drop count.
- 600 mg THC in 15 mL = 300 drops = 2 mg per drop
- 300 mg THC in 30 mL = 600 drops = 0.5 mg per drop
- 1,000 mg THC in 30 mL = 600 drops = 1.7 mg per drop
Write the per-drop number on the label with a marker. It removes the math from every future session.
What is a safe starting dose per drop?
Start with 1 mg to 2.5 mg of THC, which is one to two drops of a 0.5 to 1 mg-per-drop tincture. Wait at least two hours before adding another drop. Oral and sublingual THC can take 30 minutes to two hours to peak, so early redosing is the most common cause of a bad experience.
Does drop size change between droppers?
Yes. Glass droppers vary, with some delivering 0.05 mL per drop and others closer to 0.08 or 0.1 mL. Use the marked dropper that came with the product rather than one from a different bottle. If the dropper has no graduation marks, measure your drop volume once with a 1 mL oral syringe and adjust the formula.
What changes how one drop affects you?
- Tolerance and how often you use THC
- Body weight and body fat percentage
- Sublingual hold time versus swallowing the oil
- Food in the stomach, which slows absorption
- Other medications that compete for the same liver enzymes
- CBD content, which can soften the edge of a THC dose
How do you titrate up safely?
Add one drop per session, not one dropper. Keep the time of day and the product consistent so you can tell what changed. If a dose feels right, stay there for several sessions before increasing again. Most people settle between 2.5 mg and 10 mg of THC per session.
What are signs of too much THC?
Anxiety, racing heartbeat, nausea, dizziness, dry mouth, and paranoia are the usual signals. Oral THC effects can last four to six hours and peak around the two to four hour mark. Rest, hydrate, and do not drive. Seek medical care for chest pain, fainting, or severe vomiting.
How should you store a dropper bottle?
Keep it upright, sealed, and out of reach of children and pets. Store away from heat and direct light, which degrade THC over time. Always keep the original label so the mg-per-drop number stays with the bottle.
