Echoing the others, and coming from someone who had problems with both pot (and other drugs as well) and alcohol, there is definitely cause for concern. The first thing is that, regardless of how much you are using now, and how well you can control it, you still replaced the pot with it. That is the first sign. It can be hard to go without anything. But as long as you are medicating with something, you are playing with fire. (Not a judgement; just my own personal experience, and the experience of countless others.)
I see you are new here, and in your post you don't mention why you were a daily smoker. (Congratulations on quitting! That's a huge step!) But it's worth looking at. Is it to deal with other mental health issues? Life stressors? Just because? If you're concerned, you may want to begin to evaluate ways that you can alternately deal with these things that won't cause harm to your life, before you end up in a pattern that becomes impossible to break.
You definitely have my support, and the support of others.
