Cereal with water is weird. I like my oats with oatmilk.

Soy milk has comparable amounts of protein with dairy.

You could prepare healthy snacks before (!) smoking.

some inspiration:

-vegetable sticks with hummus/guacamole

-fruits (frozen grapes are awesome)

-roasted chickpeas

-popcorn (without drenching it in butter)

I understand where you are coming from but I don't think monthly limitations for e.g. alcohol will reduce casualties. It could even achieve the opposite. 50 bottles of beer/month would suffice for most of the population, but would also push heavier drinkers towards an unregulated black market with all of the negative side effects. Just think of methanol poisoning via homemade moonshine.

Back to cannabis: Black market dealers won't offer you help to reduce your consumption or make you reflect about your usage. Dispensaries or CSCs on the other hand could fulfill this role. And lastly, there are peope who function just fine and live a "normal" life while smoking >2g of weed a day. It feels unjust to me to still criminalize these people, as they potentially will only harm themselves.

Think of the pain scale, but apply it to beeing high lol

To be fair, medical users wouldn't be affected by the 50g limit. I guess becoming a patient will get easier after the decriminalisation/legalization.

I think the 50g/month limit only applies to purchases from cannabis social clubs. Growing your own or "buying" from a friend would still be legal ways to get over the 50g limit. I agree that there shouldn't be a limit though. Hopefully it will be increased in the future

Increasing tolerance is a thing. 50g isn't that much, if you make your own concentrates or host some get togethers at your house and smoke your friends out. I personally don't consume anywhere that much, but I don't think that we should patronize adults like that. There isn't a limit for buying alcohol or tobacco either. It only pushes heavy users towards the grey/black market in the end.
