It is most commonly used by smoking it, but it can also be incorporated into food products such as cookies. THC has euphoric effects and causes moderate perceptual disturbances. Of the side effects, there may be increased cravings, dry mouth, conjunctival congestionós, impaired time perception, impaired concentration and increased heart rate – however, they are short-lived. The effects usually subside a few hours after taking THC.

After a single use, it can be detected in the urine for about 3 – 10 days, and up to 4 weeks in the case of peopleób who use marijuana regularly, and this time can vary depending on the sensitivity of the test used. In the blood, the substance is found for a shorterótime, up to about three days. All measurements depend on how often and in what amounts the person being tested uses the substance.
