Medical Cannabis Side Effects - and How to Avoid Them

Every effective medicine has side effects - medical cannabis too. The good news is they're usually mild, temporary and largely avoidable if you start cautiously and under a doctor's care.

Below, concretely: what you might feel, why, how to limit it, and when it's worth calling the doctor.

The common and mild ones

These usually appear at the start and fade as your body adjusts or as you fine-tune the dose:

  • dry mouth
  • drowsiness or fatigue (especially after an evening dose)
  • dizziness, sometimes a drop in blood pressure when standing up
  • increased appetite
  • red eyes
  • Most are easy to limit: drink water, don't stand up abruptly, schedule higher doses for the evening.

    Rarer ones, linked to high THC

    With too high a THC dose, especially in sensitive people, you may get: unease or anxiety, racing heart, disorientation, nausea. This is almost always a sign the dose was too high.

    The rule that solves most problems: start low, go slow. Begin with a small dose and raise it slowly. Adding CBD often softens these THC effects.

    How to limit side effects

  • start with a small dose and increase gradually, under medical supervision
  • drink water - fixes dry mouth and some dizziness
  • take sedating doses in the evening, not before activity
  • don't mix with alcohol or other sedatives without the doctor knowing
  • ask for a CBD-containing profile if THC makes you uneasy
  • Tolerance to most side effects builds within a few days - that's normal.

    What not to do and when to call

    Medications with THC preclude driving and operating machinery - this isn't a side effect to ignore, it's a hard rule. Details in our article on the law.

    Call the doctor if side effects are severe, don't fade after a few days, or worry you enough that you're thinking of stopping therapy. These are things to adjust, not to endure in silence. Book a follow-up via the form or by phone: +48 731 000 645.
