2. Indica

Indica is one of the three primary types of cannabis, known for its relaxing and sedating effects. This strain is commonly used in the evening or at night to unwind and promote sleep. Indica plants have wide leaves and a shorter, bushier stature compared to sativa. They typically contain higher levels of CBD and lower levels of THC, contributing to its calming properties.

Some popular indica strains include:

  • Northern Lights
  • Granddaddy Purple
  • Purple Kush

3. Hybrid

Hybrid cannabis is a blend of both Sativa and Indica strains, offering a mix of their effects. When choosing a hybrid strain, consider the balance of its parent strains’ characteristics, such as the potential for relaxation from Indica and the energising effects of Sativa.

Hybrids can be further categorised as:

  • Indica-dominant
  • Sativa-dominant
  • balanced

each offering varying effects.

How Does Cannabis Affect the Cardiovascular System?
