I started buying hemp & CBD products online a few years back. There was a law that legalized industrial hemp as long as it had less than 0.3% of THC in it. Although there was some ambiguity with the style of the law, it basically started a sizable national CBD industry overnight. My local head shop & tobacco store started selling these CBD concentrate butters that could be vaporized in a cannabis oil vaporizer. I was buying them then, however they were so famous that it was hard to get on the priority list before the stock would disapplum for another week or several. Many of us were also sad to varying degrees about the legality surrounding it all. In reality, the 2014 Farm Bill was ambiguous & some questioned if there were as numerous legal protections for CBD companies & users as every one of us initially thought. Thankfully that ambiguity & debate was put to rest with the 2018 Farm Bill. It took CBD & linked it from the list on the Controlled Substances Act & got rid of its DEA classification as well. As long as the hemp & CBD products are sourced from plants with less than 0.3% THC inside, they’re considered a separate style from traditional marijuana with more than 0.3% THC inside. Now you don’t even have to worry about going on planes with CBD products, as they are protected by federal law. I believe some people who take advantage of this & fly with their high THC products purchased at cannabis dispensaries, however that’s a gamble for sure. Your TSA agent that day might not care, but won’t know it until the moment of truth.
