K2, also known as Spice, is a mixture of herbs, spices, and synthetic cannabinoids that are similar to THC, the psychoactive compound found in marijuana. K2 is often marketed as fake weed or synthetic marijuana and is sold in bags labeled as incense. One common form of K2 is in spray or sheet form.

K2 Spray:

K2 spray refers to a liquid form of the synthetic cannabinoids that are typically sprayed onto plant material or infused into papers. These sprays may contain various synthetic compounds that mimic the effects of THC.
The liquid spray form allows for easy application onto herbs or paper, which can then be vaporized or smoked.
Some popular names associated with K2 spray include Bizzaro Liquid Incense, Klymaxx, Kratom Green Blossom, Mad Hatter, Nice Guy incense, Pink Blossom, Green Giant, and White Tiger.

K2 Sheet:

K2 sheets are special A4-sized papers that have been infused with synthetic cannabinoids. These sheets may be odorless and colorless, making them discreet for use.
Users may roll these infused sheets into cigarettes or joints for smoking purposes.
The quality of these sheets can vary, with some being marketed as grade AAA quality.

Both K2 spray and sheet forms are part of the larger market of synthetic cannabinoids that attempt to replicate the effects of marijuana. However, it’s important to note that these substances can have unpredictable and severe side effects on users due to the unknown composition and potency of the synthetic compounds used.
