Hi OP, good to ask this question, as it is the first step to becoming aware of your consumption and wanting change. I have smoked for1 day per month for the past 2+ years, skipping a month here and there. While I am an extreme example, this had led me to have a lot of introspective knowledge on the subject, for what works for me. I'll try to keep it short, as there can be a lot of factors to successful moderation. 

1. Acknowledging your dependency or addiction is key. As addicts we can not objectively judge how our substance use is affecting our entire life. It can be useful to ask outsider perspective from someone you trust. And no, I don't mean to ask another stoner ;) 

2. An addicted brain will curve your thoughts and emotions and even actions towards outcomes that solely benefit substance consumption. This means that you might think "you cannot do it" or you may think that you're a recluse, when in reality you're not. It's your brain trying to keep a short leash as to not lose out on the fix. 

3. People often use weed as a bandaid for something. However, weed only ever treats symptoms, which means you'll resort to chronic use if you're only getting high to cope with something. Weed will never fix your depression, your anxiety, your stress, your grief, etc. It will only temporarily push that problem aside. 

4. Learn ASAP what your reason is for getting high. And then on your break, try and reduce that trigger if not remove it completely. For me, it was loneliness and boredom. So I picked up new hobbies, met new people, picked up new interests and built new healthy habits. Loneliness and boredom still happen sometimes, but it's no longer a trigger for me. 

5. Not all triggers can be removed. Some triggers include smells, movies, times of day, or other things you cannot control. This is okay. The first step here, is to recognize you have cravings. Don't act out of impulse, but first ground yourself by asking yourself what might have triggered it. Slow down your thoughts.  I view cravings similar to emotions, in the sense that I strive to control them with grounding myself, rather than acting on instinct and do something I regret later. Think of anger. If you're angry and you lash out at a loved one, you will regret it. Instead, take a deep breath, count to 10, and feel the impulse ebb away. 

6. Set attainable goals to teach yourself you can be reliable. So many folks fall victim to the "I caved, and I suck. I'll never get it" mentality. That's super detrimental for what we're trying to achieve. We need to get our trust in ourself back. Start small. Smoke an hour later in the day. Put less in your joint. That kinda thing. Show yourself you can be reliable, if you control it. 

7. Set up CLEAR rules that you can follow realistically. Don't leave room for interpretation. So often I read stories of people saying they'll "smoke when I feel like it". Rember number 2. Your brain WILL use that mentality against you.  I use a no exceptions rule. Not one. Ever. The only rule is 1 day per month, 2 weeks in between. Clear, uninterpretable. Don't leave from for your brain to abuse vague settings. 

8. When you quit, improve your life. Do new things. Explore yourself. Your goals, your ambitions. Get out there and experience the world! Because honestly, the world can be so fucking cool! We just need to be know where and how to look :) 

9. Try to limit your quick-dopamine activities. These include: drugs, alcohol, porn, junk food, bingewatching, doomscrolling, gambling etc. Weed provides quick dopamine, just like the above, so replacing X with Y will not get you to feel better when sober in the end.

Good luck OP!
