Thanks for the advice. I'm leaning towards the idea of simply letting her smoke rather than use edibles, and to share a joint with her rather than letting her smoke a spliff (weed/tobacco mix) as although a spliff has less Cannabis in it and is milder, the stimulant effects of nicotine seem to heighten paranoia and anxiety, producing a much less clean high that is more prone to be a negative experience.

There aren't too many high grade Indica strains available for people looking around here other than in the case of growing your own, but she will be moving to Poland next year and so when I visit I should be able to find something as Indica strains are much more common there, along with good hash which comes straight from Nepal/Afghanistan/etc. Poland may be enacting medical marijuana laws of their own soon and hopefully these may come into place before she moves there, allowing her to avoid the black market.

Thanks again, and any extra advice is greatly appreciated.
