i have eczema. last year i was very ill and had an allergic reaction, but i never stopped smoking weed. then i went to italy this in the summer, which cleared my eczema, i decided to stop smoking weed and i have been fine since. i smoked weed this weekend which i havent done for ages and for the past week ive had the worst allergic reaction. my face is all red swollen and it has been getting spreading to my arms, tummy and back. does this mean im allergic to weed? and what can i do to stop it spreading and make it better before i go to the doctors on monday?
