are electric cigarettes better than tobacco?

[Hhhhbhhb]

im 18 ive smoked weed for almost 3 years, everyday unless i was out.
the start of 2013 i decided to stop weed, as i noticed it was not being as positive on me as it was and my confidence and my social skills where being degraded alot, me being a quite person anyway the weed made me further. my head started feeling clouded and just messed up, heavy pressure in my head, and just zoned out, but the weed wasn't addictive i didn't get any cravings but their where these negative effects, i noticed at the end of the year, so decided to stop, ill see how long that takes.

ive got weed left havent even craved any at all. the first two days i stopped smoking weed, i had terrible vivid dreams which i couldn't go back to bed, they where that bad.

anyway ive been smoking tobacco, it helped me as its a stimulant and just helps me more energetic and talkative and alert, it helped forget about weed and ive basically got bored of weed. but im now worried of doing tobacco because of the tar and cancer, so i switched to e ciggs, ive felt very good, just top up when ever i want, just feel normal like i did before weed or when i take a coffee. i have mild depression aand ive heard nicotine helps people with mental illness cope with their illness, even schizophrenics, and even makes you more alert.

so i wondering despite nicotine being addictive, is their any other ill effects from these e cigarettes?

also get no buzzing effect from e ciggs whiich i do from tobbaco which i quiet enjoy, but i get none from eciggs is that normal, i thought nicotie cause this, or was that the cause from all the junk in the tobbaco?
