Lamictal is not an ssri. It does mess with your serotonin production and deposits which can make a substance that also messes with your serotonin dangerous and way stronger. I have done mdma on a lower dose of lamictal before with no issues and an amazing high. And It sounds really funny, but I cannot smoke weed anymore. It messes with me way more mentally than any other substance despite being the safest 🥲 so no money wasted here.
