What Is Cannabis Syrup?

Cannabis syrup is a concentrated, sweetened liquid infused with cannabis extract, most often THC. It can be consumed on its own, added to beverages like iced tea or lemonade, or mixed into cocktails. Sold in bottles with a dropper or measurement cap, it is designed for modular dosing. In many ways it combines the effects of an edible with the convenience of a drink mixer.

Because THC syrup is processed by the liver when swallowed, effects take longer to arrive but last considerably longer than inhalation. For this reason, it belongs to the broader category of edibles. Depending on the formulation, a bottle may contain 100mg to 1000mg of THC, so checking the label and calculating a per-milliliter dose are essential.

Answer at a Glance

If you want the short version, here it is: THC syrup is a drinkable edible that typically starts working in 30 to 90 minutes, peaks around two to four hours, and can last six to ten hours. Most brands suggest starting with 5 to 10 milligrams of THC and waiting at least two hours before taking more.

How Cannabis Syrup Works

Cannabis syrup is absorbed through the digestive tract, not the lungs. When you swallow it, the liver converts THC into 11-hydroxy-THC, a metabolite known to produce a more sedative, full-body experience. Some users also consume a small amount sublingually—holding it under the tongue—which bypasses some liver metabolism for faster onset.

How to Use Cannabis Syrup

Measure carefully. Use the dropper or cap that comes with the bottle. Decide on your starting dose. Mix it into any liquid, or take it straight. Do not mix it into hot drinks at the point of consumption because heat can degrade or evaporate some cannabinoids, although decarboxylated syrup is already active.

Dosing Guidelines

  1. Start low and go slow. Beginners should use 5mg or less.
  2. Calculate the dose in your bottle. For example, a 300mg bottle with 60ml contains 5mg per milliliter.
  3. Certified drink mixers often have their own dropper measurements, but do not rely on them; check the packaging.
  4. Wait two hours before redosing. Eating a fatty snack may increase absorption, but it can also delay effects.

Onset and Duration

On an empty stomach, you may notice effects in 30 minutes. After a heavy meal, onset can take closer to 90 to 120 minutes. Peak effects usually occur between two and four hours. The total duration is typically 6 to 10 hours, and some people report residual drowsiness the next day. That is normal.

Safety Considerations

If you are new to THC drinks, treat cannabis syrup like any other edible. Read the label, verify lab testing, and choose a dose that matches your tolerance. This guide is not medical advice; consult a clinician if you have questions.
