Hey there

It's a pretty well-known phenomenon that addicts will use more substances throughout the winter. This is mostly in reference to regions that have seasons, especially with rugged winters. For instance, I'm from Boston and I currently live in Vermont. It's understood among social workers that there will be more problems during the winter. When people are more confined, they tend to go crazier.
Covid-19 was a good example. People being more restricted to their homes caused a massive increase in substance use, specifically addictive/compulsive usage. What I mean by that is people deciding to use substances in the face of stress/anxiety are almost inevitably harming their mental health. It might not be "addiction" but it's not a positive response to these feelings.
This could be OP using more Cocaine, I'm assuming her drug of choice. It could also be a housewife having a whole bottle of wine every night instead of a couple of glasses. Winter is pretty much the same thing. Pretty much anything that can be done in the summer can be done in the winter... that doesn't mean people want to be doing it. Even "outdoorsy" people don't feel like standing around in 0F weather.
As we know, when we lose enrichment in our lives, our more basic urges can steer us into negative directions. They also say just the reduction in sunlight is enough to make people depressed. I think it's mostly due to less activity, mentally, physically etc. You have to prepare for winter by having stuff you can do that you enjoy.
You have to go outside, even if it's cold. If you don't like jogging, maybe you can ski, build a snowman, I got a dog myself and she keeps my active and having a purpose. She makes my winters that much better.
