Abstract: The invention involves transforming Cannabis with a transgene(s) or chemical(s) expressing biological, chemical, luminescent, and fluorescent markers from the UV, visible, near, mid, and far spectrums of light. This transformation allows for the detection of Medical Marijuana from other forms of marijuana. Cannabis is a genus of flowering plant that include three putative species Cannabis sativa, Cannabis indica, and Cannabis ruderalis. The invention relates to seeds, plants, plant cells, plant tissue, and harvested products from transformed Cannabis. The invention also relates to plants and varieties produced by the method of essential derivation from plants of transformed Cannabis and to plants of transformed Cannabis reproduced by vegetative methods, including but not limited to tissue culture of regenerated cells or tissue from transformed Cannabis.
