Crip: Is an american slang term, popularised by Dr Dre and various other rap artists. The word crip, is a verry widely used word among the youth with various possible origins. it is used to describe a particualr scent and set of characteristics exibited by a number of strains. One possible origin is through connections with the crypts, a wide spread street gang, though this is doubtfull. It has been said that it was a nick name given because of the saying "it is so good it criples your thoughts" because of it's high potency. Another possible origin is jargon refering to bud with decent crystilization or a mispronounciation of chrispy due to cotton mouth sounding like crippy being shortened to crip for ease. It does not describe a particular strain and generaly describes high quality, seedless sensamillia. Crip weed is known for it's pugnant, crisp, citrusy sent usualy unable to be contained by a single ziplock bag.
Your typical "crip" weed refering to cannabis that is most commonly indica of the purple, blue or dark green types. The crystals are usualy light or white usualy, with a high that lasts from 4-6 hours. Side effects from this type of weed may some times innitialy causes a burning feeling in the eyes, extreme dehydration, and paranoia[from blue strains], but that happens with all weed to an extent.
Chronic:
Now days chronic gets thrown around by hundreds of people as a catch all term for realy great weed, but chronic is not a term to be thrown around lightly. Pupularized by Dr Dre's 1992 album titled The Chronic, a strain called hydro-chronic won 3rd place at the 1994 High Times Cannabis Cup spreading seeds to countless farmers. It is dark green with red or dark brown hairs it has exceptionaly thin yet suprisingly supportive, purple stems. New age "chronic" has a verry sharp scent that almost bites your noise, for this reason it is known to cause you to cough, leading to elevated heart rate. The increased the speed that THC goes to your brain causes an elevated rush. It is 100% indica with a hint of purple on the lower, inside of the nugs.
A typical high from "chronic" based strains lasts 8+ hours and has been known to cause a "greenday" or weed hangover the next day even in some who who normaly smoke every day. Like the medical definition of chronic the high long lasting and persistant with a peak 30-60 minutes after it's use leading to over consumption.
There may be many reasons you feel paranoid while smoking, but one may just be that you personaly shouldn't smoke weed in social environments. For some people it slows down thier brain and makes it hard to keep up with the conversation and on top of that it's not any easier when your mouth is a desert. Another reason for the paranoia might just be WHO you are around while you are smoking, or the environment you are in. If it is a sketchy situation or you don't feel like smoking is a good idea you realy don't have to and probably shouldn't. If you feel that smoking is causing a problem for you in a social sourounding then maybe try smoking less. Unless you have a medical condition you have no NEED to smoke. Try only smoking 1-3 hits and seeing how that works out. Also it might just be simply be because you are smoking indica's and like to smoke sativa's. Sativa's are known to produce a more energenic, bubbly feeling, maybe this is what you are looking for. they tend to be better in a more social sitiation with less mental effect. But realy, if you feel like it's a problem, you realy shouldn't be making a habit out of it like BottleOfOxy sugested.
good luck figuering stuff out and stay safe.
