THC Strains — every major THC variety at a glance

THC strains are the classic cannabis varieties high in tetrahydrocannabinol — psychoactive, versatile, with distinct Indica, Sativa or hybrid profiles. This hub links to every major strain in our encyclopedia.

TL;DR: THC strains usually contain 15–28% THC and form the backbone of global cannabis culture. In Switzerland they are only legally accessible through the controlled pilot trials or a medical cannabis prescription — but CBD versions (< 1% THC) of many of these genetics are freely sold.

What is a THC strain?

A THC strain is a cannabis variety whose main active compound is THC (tetrahydrocannabinol). Typical values are 15–28% THC at under 1% CBD.

Within the group you'll find Indica (relaxing, physical), Sativa (energetic, cerebral) and hybrids — each with different terpene profiles that shape aroma and effect.

Legal status in Switzerland

THC-rich cannabis flower (> 1% THC) is not freely sold in Switzerland. There are two legal pathways:

1. Controlled pilot trials (Basel, Zurich, Geneva…) — time-limited studies for enrolled adults. 2. A medical cannabis prescription since the 2022 BetmG revision — no FOPH permit needed.
