Maryland’s cannabis industry is less than two months old and lawmakers and regulators are already contemplating tweaks in the coming General Assembly session. Since July, the new recreational adult use industry has recorded sales of almost $90 million. The expectation is that sales will surpass $1 billion. Will Tilburg, acting director of the Maryland Cannabis Administration, said the new law — which runs roughly 100 pages — was an attempt to learn from the mistakes of other states that legalized recreational use before Maryland.
