here are many ways to roll tobacco or canibis, this is one way from Gibraltar. Please be nice, this is my first video that i have made – i tried adobe premier and it ws just too hard to wor out (im not reading any instructions!) Film was made in windows movie maker. **Disclamer** This is an instructional video only. Canibis use is against the law, the green substance used in this film was NOT canibis. Smoking tobacco and or canibis can have long term undesirable effects – dont do it!… Cannabis was one of the first plant species to be karyotyped however this was in a period when karyotype preparation was primitive by modern standards see History of Cytogenetics.
