Issues with smoking flower

So.. every time I smoke flower marijuana I feel very odd.. I get a fast heart rate and just don’t feel right. It lasts like 5/10 mins then I’m good and feeling good but I don’t get like this with the vapes. I’m not a major smoker either i recently just started but was wondering what the difference is between the vape and flower that’s causing me to get like this with just flower. It’s frustrating because I love the feeling I have with the vapes but the flower just doesn’t agree with me for some reason. Does anybody else get like this? Also my boyfriend says the vapes don’t even get you “high” but he’s dead wrong lmao Is there a big difference between flower and vape?
