Weedgender is a druggender affected by being under the influence of THC (known colloquially as weed). This could be smoking, vaping, dabbing, or edibles. Those who identify as weedgender may feel more connected with their gender while under the influence, or feel a different gender entirely.
Hempgender
Hempgender is a more broad version of weedgender which includes weedgender's definition, but also includes CBD, another hemp product. Hempgender and its flag were coined by Fandom user Raining Stars Collective.
History and Flag
Weedgender's source, Druggender, along with its flag, was coined by tumblr user Gender-Garden on July 30th, 2018. The Weedgender flag was created by Fandom user MiamiHotlines on June 30th, 2021 and is an edit of the original Druggender flag.
Druggender was most likely created as a joke identity, but could be reclaimed by individuals who use drugs. (For example, smoking marijuana to help with mood or overstimulation.)
Usage of Hemp Drugs
There is a really negative stigma around the usage of hemp products like THC and CBD, but this is a stigma based in racism, as they've been used to villainize people of color, especially Black and Latine people of color, who use the products. In reality, the opportunities for benefitting from using hemp products greatly outweigh potential health risks, which are associated with all drugs and do not make hemp products bad or shameful.
Drugs like CBD and THC are known to have healing affects for many different psychiatric and neurological disorders/conditions/illnesses/etc. such as PTSD, epilepsy, anxiety, and others, and in many cases are becoming more common methods of medication treatments for people with these issues.
Psychiatric Disorders
Marijuana products have been found to help people with psychiatric disorders (anxiety, depression, PTST/PTSS, etc.) They have been shown to help people with PTSD/PTSS sleep better and cope with flashbacks, as they have a dimming effect on memory and memory-related stimulus, which helps people with PTSD/PTSS to not have as strong flashbacks and reactions to them.
Similar to how it has been shown to help in people with PTSD/PTSS, medical marijuana has been shown to held drastically with reducing both initial stress, and with secondary reaction to stressing stimulus, in people with anxiety disorders.
Side effects of the usage of these products for psychiatric help are not very serious but include fatigue, sleepiness, memory and appetite issues, among others.
CNS (Central Nervous System) Disorders
Medical hemp products (cannabis/marijuana) have been found to have a wide range of significant benefits to people with CNS disorders like epilepsy, Multiple Sclerosis, Parkinson's Disease, and Tourette's Syndrome. The CBD in many medical hemp products has been found to greatly relieve seizures in people with epilepsy, and have helped with many symptoms with people with CNS disorders.
Autism
While autism is not a disease and the stigmatization of it as one is harmful and even fatal for autistic people, it does involve some more negative symptoms like depression, rage attacks, tics, seizures, and restlessness, and in children 18 years and younger, medical cannabis has been shown to help relieve those negative symptoms in a vast majority of autistic children.
