Taking cannabis from Koh Samui to Krabi via ferry and bus

Just wondering what the security is like and if it's even worth it. I don't have much just a grinder , like 2 grams and some rolling papers. I know it's apparently illegal but I have been in bangkok Chiang mai and now Koh Samui in the past couple weeks and see dispensaries everywhere and have been able to buy it no problem. So not really sure on how illegal it is lol. If it's a big deal it's no problem to toss it but just hate wasting it y'know.
