A weed is a plant considered undesirable in a particular situation, “a plant in the wrong place”. Examples commonly are plants unwanted in human-controlled settings, such as farm fields, gardens, lawns, and parks. Taxonomically, the term “weed” has no botanical significance, because a plant that is a weed in one context is not a weed when growing in a situation where it is in fact wanted, and where one species of plant is a valuable crop plant, another species in the same genus might be a serious weed, such as a wild bramble growing among cultivated loganberries. In the same way, volunteer crops (plants) are regarded as weeds in a subsequent crop. Many plants that people widely regard as weeds also are intentionally grown in gardens and other cultivated settings, in which case they are sometimes called beneficial weeds. The term weed also is applied to any plant that grows or reproduces aggressively, or is invasive outside its native habitat. More broadly same day weed delivery Calgary occasionally is applied pejoratively to species outside the plant kingdom, species that can survive in diverse environments and reproduce quickly; in this sense it has even been applied to humans.

Cannabis contains over 140 cannabinoids – chemicals that affect how our brain functions and affects our mental state and physical movements.
The most abundant cannabinoids found in cannabis are THC (tetrahydrocannabinol) and CBD (cannabidiol).
THC (tetrahydrocannabinol) and CBD (cannabidiol) are cannabinoids, chemical compounds found in cannabis. Cannabinoids change how signals are sent in our brains and affect our mental and physical state.
THC is found in higher concentrations in non-medical cannabis. It is the main psychoactive compound of cannabis, meaning it changes our brain function and our ability to think, our mood, and our behavior.
The concentration of THC in cannabis products can vary. Since THC is the compound that causes impairment, it is important to know about the product you are using. The THC concentration in dried cannabis has increased from an average of 3% in the 1980s to around 15% today. Some strains can have as high as 30% THC. This is why it’s important to know what you’re using and practice Safer Use.
CBD is found in higher concentrations in medical cannabis. It is mainly used for its therapeutic effects for reducing pain and inflammation, nausea, anxiety, seizures, and spasms.
