Can different cities cause acne ?

I just moved in with my parents after being out of their house for 3 years. During those 3 years I was in a city about 30 min away never had a single pimple. Now I’ve been back 3 months and it seems like I get 1/2 bumps on my face every other week. I wear the same selection of clothes and wash them along with my bed sheets once a week, the same as ive been doing for 3 years. Nothing about my diet, schedule, or the rate/how I wash has not changed. As a matter of fact, the Only thing that has changed in my life that my weed intake went from smoking 1 or 2 times a day to maybe once every other week now. What is a possible cause of this sudden acne when nothing has changed besides a 30 min difference in where I live?
