||Cannabis is rarely laced with anything. The main signs to look for if you suspect adulterants would be odd taste or smell, or a dramatic change in the duration of effects. As with most psychoactive drugs, cannabis can cause a wide variety of reactions in different people and at different times. There is also a broad range of potency and types of cannabis, which will cause different types of effects. |
People definitely experience strong visual and mental effects with cannabis, rivaling anything one could experience with other psychedelics like LSD or mushrooms. Of course, most commonly the effects are not this strong. If you find yourself experiencing undesireably strong effects from smoking cannabis (you might be a person with a high sensitivity), you might want to try lowering your dosage.
