Medical Cannabis 101: What Patients Should Know
Cannabis contains dozens of active compounds, but two get the most attention in a clinical setting: THC and CBD. Understanding the difference helps you have a more productive conversation with your practitioner.
THC (tetrahydrocannabinol)
THC is the primary psychoactive compound in cannabis — it's what produces the "high." In a medical context, practitioners consider THC content carefully, since higher concentrations mean stronger effects and a greater chance of side effects like anxiety or impaired coordination, especially for first-time patients.
CBD (cannabidiol)
CBD is non-intoxicating and is often discussed alongside THC for its potential to soften some of THC's more intense effects. Products with less than 0.2% THC are treated differently under Thai law and face far fewer restrictions than higher-THC flower.
How practitioners think about matching therapy to patients
There's no universal "best" product — a practitioner will typically consider:
- Your specific symptoms or condition
- Prior experience (or lack of experience) with cannabis
- Other medications you're taking, to check for interactions
- Method of use and how quickly you need effects to take hold
- THC-to-CBD ratio appropriate for your tolerance
What to expect the first time
If you're new to cannabis, most practitioners recommend starting low and slow — a smaller amount, monitored closely, before adjusting. This is part of why an in-person consultation matters: dosing guidance is genuinely individual.
