Key Insights

• 🧠 Cannabis enters the bloodstream and permeates throughout the brain and body within 30 seconds of consumption.
• 🙊 The effects of cannabis peak within 30 to 60 minutes and can last up to four hours.
• 👻 THC, CBD, and other components of cannabis are highly lipophilic, allowing them to pass through fatty tissues and remain in cells for a prolonged period.
• ❓ Different strains of cannabis, such as sativa and indica, have varying effects on mood, focus, and relaxation.
• 🧠 The effects of cannabis are mediated through the activation or suppression of CB1 receptors in various brain regions.
• ❓ Predicting the effects of a specific strain on an individual is challenging, as there are no reliable predictors.
• ❓ The dosage and method of consumption can affect the intensity and duration of the effects.
