The dropper is the point

A tincture is cannabis extract in liquid form, most often with an alcohol base. You measure it with a dropper, then either hold it under your tongue or swallow it. Because the dropper makes small steps easy, tinctures are the form to look at if you like to adjust a dose gradually. There is no smoke and very little smell, which suits a city apartment. The label lists THC and CBD per dropper or milliliter, and that number changes from product to product.

Under the tongue or swallowed

How you take it changes the timing. Sublingual use is generally felt sooner than swallowing, while swallowed tincture behaves more like an edible, with a slower and longer onset. Either way, the rule is the same as for any edible: go slowly and give it time before you take more.

  1. Read the THC and CBD per dropper on the label.
  2. Measure the smallest amount it describes.
  3. Take it the way the label directs.
  4. Wait at least two hours before you decide on more.

Balanced THC and CBD tinctures list both amounts, so you can see the ratio before you buy.

RSO is a different animal

RSO, short for Rick Simpson Oil, is a thick, dark oil, very concentrated, and a piece the size of a grain of rice is a meaningful dose. It is made with a solvent such as alcohol that is evaporated afterward. It is hard to measure precisely, so it suits people who already know concentrates. If you have a medical condition or take medication, talk with a healthcare provider before using RSO. What is RSO oil has the background.

When the menu comes up empty

Tinctures and RSO come and go. If neither is listed today, an edible with the dose on the label is the nearest easy way to measure.

Good To Know

RSO & Tinctures FAQ

How is a tincture different from an edible?

A tincture is a liquid you dose with a dropper, so you can adjust in small steps, while an edible comes in a fixed piece. Swallowed tinctures act like edibles, with a slower and longer onset. Read the label for the THC and CBD per dropper before you measure.

Is RSO the same as a tincture?

No. RSO is a thick, dark, very concentrated oil dosed in rice-grain amounts. A tincture is a thinner liquid you measure with a dropper. RSO suits people with concentrate experience, and a tincture is the easier one to measure. Read the label on whichever you choose.

How much RSO or concentrate can I buy?

Adults 21 and older can buy up to 15 grams of concentrate per transaction, inside the 2.5 ounce total limit. Every adult-use purchase needs a valid government-issued photo ID. Never drive impaired, and keep it away from children and pets.
