Marijuana is at the heart of many legal controversies. As more states continue to locally legalize medical and recreational use in defiance of federal laws, we can expect more rapid law changes and court rulings that affect how employers drug test and what rights employees have with regards to marijuana.

On way to stay on top of these laws is to follow the Twitter accounts of industry leaders and experts. This list was compiled after reviewing tweet content, follower numbers, freshness of information, and other indicators. Note that we could not include all influential voices, some because they don't use Twitter, and some because they only tweet sporadically. Our goal is to provide you with a list of accounts to follow in order to keep up to take on the best information.
