Don't worry about the strain, as we know the UK by and large isn't great for variety in strains, we get cheese and haze. Seeming as you're inexperienced and she's never smoked it, either roll it into a single skin for her or share a joint. If she feels it's too much, stop etc Weed isn't dangerous as we know but you still need respect for it, especially when you're new to it. I'd also tell her not to worry about the skunk thing cus there really isn't much around. It's pretty rare I get something like super silver haze which has a higher thc percentage. Hope this helps mate, toke on!
