How do you use cannabis oil?
Place the measured dose under your tongue, hold it there for 60 to 90 seconds, then swallow. That route, called sublingual, sends cannabinoids into the bloodstream through the tissue under the tongue and skips most of the digestive breakdown. Effects usually show up in 15 to 45 minutes and peak around 1 to 2 hours. Swallow the same dose like a capsule and the timeline stretches: 30 minutes to 2 hours before you feel anything, with a peak closer to 2 to 3 hours.

That one difference explains most bad first experiences. People swallow a dose, feel nothing after 20 minutes, take more, and then everything lands at once.
Sublingual: hold, then swallow
Use the dropper against the inside of your cheek or under the tongue. Try not to wash it down with a drink for a minute or so. A dry mouth slows absorption, so take a sip of water first if you need to. Oil carried in MCT or hemp seed oil spreads and absorbs well; thick, dark extracts can be sticky and harder to measure, which is why a marked dropper matters.

If you swallow it instead
Swallowed oil passes through the liver before it reaches circulation. That first pass converts THC into 11-hydroxy-THC, which is more potent and lasts longer, and it converts CBD into 7-OH-CBD. The practical takeaway: the same milligram count hits differently depending on whether you hold it or swallow it. Pick one route and stay with it for a week before you judge the dose.
Start low, and write it down
For CBD, 5 to 10 mg once or twice a day is a common starting point. For THC, in places where it is legal, 1 to 2.5 mg is the usual first step. Keep notes: date, time, milligrams, route, and how you felt at 1 hour, 3 hours, and the next morning. Patterns show up faster in writing than in memory. If nothing changes after a week at a steady dose, nudge it up rather than jumping.
What the label and paperwork should tell you
- Total cannabinoids per bottle and per dropper, not just per "serving."
- Whether it is isolate, broad spectrum, or full spectrum, since full spectrum carries trace THC and other cannabinoids.
- Carrier oil, usually MCT, olive, or hemp seed oil.
- A batch number that matches a certificate of analysis from an accredited lab, dated within the past year.
- Testing for potency, pesticides, heavy metals, residual solvents, and microbials.
Storage and handling
Heat and light degrade cannabinoids. Keep the bottle closed, upright, and out of the sun, in a cool cupboard rather than the car or a windowsill. Shake before each use, since oil separates. Check the expiry or retest date. Keep it locked away from children and pets; a chewed bottle is a veterinary emergency.
Interactions and cautions
Cannabis oil is not inert. CBD inhibits several CYP450 enzymes, the same family that clears many prescription drugs. Grapefruit does something similar, and the combination can raise blood levels of the other drug. Talk to a pharmacist before mixing oil with blood thinners such as warfarin, seizure medications such as clobazam, or immunosuppressants. Skip it if you are pregnant or breastfeeding. THC can impair driving and worsen anxiety in some people, especially at higher doses.
A realistic first week
Expect subtle rather than dramatic. Sleep, appetite, and background tension are the things people notice first, often in that order. Give each dose two hours before deciding what it did. If you feel lightheaded, dizzy, or unusually drowsy, stop, eat something, and wait it out. The effect fades.
