Indica and sativa plants are believed to have different effects on their user. These effects include:
- relaxing and calming
- body buzz or ‘couch lock’
- best suited for night use
- uplifting and energetic
- cerebral, spacey or hallucinogenic
- best suited for day use
No scientific study has set out to confirm these differences. But many patients and plant breeders support their accuracy.
Sativa and indica plants have different chemical profiles. Sativas are usually rich in CBD while indicas are usually rich in THC. CBD and THC are the two main compounds in cannabis and are responsible for its medicinal effects.
Based on their cannabinoid levels, sativas and indicas may be better suited for different ailments. For example, THC-rich indicas are often used at night to aid with insomnia, while sativas are known to promote wakefulness.
However, no study has compared sativas and indicas for treating specific conditions.
