Dollar Tree

I was at this store on 2/23/19, the store was reeking of marijuana. This is not the first time this has happened. We complained to the clerk, thinking it was a customer. This last time however, the cashier was reeking of the smell. There were very few customers in the store, so didn't know where it was coming from till checkout time. I take medication, that I get drug tested for, and I don't appreciate being exposed to drugs I do NOT do. The one cashier checking me out was named Deborah. I didn't catch the other lady's name. I shop at this store frequently, and am so disappointed in this issue. I don't feel I should be subjected to illegal drugs that could cause me to lose my medications, because of that getting in my system. You could obviously see she was under the influence, she could hardly work the register, very nervous, and confused.
