What exactly can they sell?
Though the state has now doled out a few licenses to operate dispensaries, no one in Texas is actually legally getting high. The Compassionate Use Act only permits for the sale of “low-THC cannabis” that must contain 0.5% THC or less, and no less than 10% cannabidiol, or CBD. For comparison, federal law allows hemp products, which are legally available for purchase online, to contain 0.3% THC.
Dispensaries may only sell medical cannabis in the form of cannabidiol oil, and under no circumstances is smoking marijuana permitted in the state of Texas. Only licensed dispensaries may grow it, and they may only do so with the intention of processing it into the specified low-THC oil.
"Whether it's 0.5 or 0.7 or 1 or 2.5, you could argue that that is an arbitrary number because it affects people differently,” says Denton. “You have to have a standard somewhere. Where Texas has set that standard is where Texas has set that standard. There's plenty of research and science that suggests that a higher concentration of THC is more efficacious for people with a variety of conditions, but that doesn't necessarily mean that it needs to be 5% or whatever. I think the concern is that the state didn't want to have any amount of THC in it that could lead a person to have a psychological reaction."
