Can marijuana give you headaches in the morning?

if you have brick weed, and smoking seeds then yes

It's your third eye opening. Trust me, I have experienced this and I know it can be uncomfortable at first but ultimately the results are usually good.

it's more likely all the HFCS you've had in soda pop.

hell no! maybe at the worst a fuzzy feeling in your head, but never a hangover or headache.

Your dehydrated and tripping the fuck out every night. Might not be bad, but be careful. Not abnormal, I do it too sometimes. Not the weed, dehydration from acting the fool and tripping the fuck out in your room. I usually don't get that high but might do so right now if I don't drink water. I have to go drink water as to avoid this problem currently. If your having this problem water or better yet OJ or chocolate milk is the answer to your problems. Next time you get this baked have a bottle of chocolate milk handy. Tastes trippy as fuck too

It's certainly possible, but not what I'd call a typical occurrence with dope. As others said, ensure you're well hydrated and your sugar levels are all good

Try drinking more water.

No, I really can't say I've ever felt that effect though I imagine it is possible. Do you get headaches when you're hungry or have low blood sugar? Yep, same thing.
