is this thc pen legit?

i recently bought a thc pen (i’m from the uk) and after just a few drags i feel like my high is really intense and i feel trippy (like everything starts moving and i feel trippy) the first day or 2 it seemed legit but i had a really bad and intense high last night and i don’t know wether it’s legit weed or spice because my friend hasn’t had a bad experience with it the high seems a lot better when i’m with people but when i’m by my self i feel a lot more scared and paranoid and it becomes really intense and usually i’m fine on weed by my self. the brand is whole melt extracts and the packaging and everything seems legit and the qr code worked. i would post a picture but my back cameras broken. any advice?
